Is it possible to aggregate the tire issue discussion here or is there one someone with just the tire issue discussed?

Goodyear is coming out with a slightly lower speed rated tire (rubber not so soft) which will probably wear longer. All that said the Goodyears don't seem to be that great of a tire - when I lifted the old ones into my truck they were remarkably light. Heavier tire = more rubber = better tire. Subscribe to the land rover tech info site its well worth the money.
I did - Budds in Oakville, ON just replaced the tires for me a few weeks ago, free of charge. Same issue exactly, noisy Goodyears. I have new Goodyears now/
tidester, host
What rules do I need to follow to get something like a 16 or 17" steel rim with offroad or winter tires.
I don't have the exact spec of the tire sizes with me, but just at a guess - 235/50/R19 would read to me like 235mm wide, side profile is 50% of that, rims size is 19" - so the total diameter would be 19" plus 117.5mm (4.6")for a grand total of 23.6 inches?
If I wanted a 17" rim, I would need a side profile of 6.6 inches... or for a 16" rim, a side profile of 7.6 inches?
I understand that I need to try and maintain the same outside diameter to keep the speedo and odometer accurate. not sure if a different tire will affect the traction systems / ABS / etc?
I could just buy 19" off road tires, but I didn't want to switch tires on and off of the original rims all the time, and wanted to keep the winter/offroad tires on their own rims. If I'm buying new rims, buying a smaller rim and tire is cheaper than buying rubber alone for a 19" tire.
Also, you can't deflate a 19" tire very much for offroading... with a 16 or 17" with a wide side profile, I can deflate them lots and get lots of extra grip.
Can someone recommend a good tire solution for this?
Thanks in advance!

235/50/19 would be 2 times 50 percent times 235 plus 19
this equals 235 mm + 19 inches = 9.25 in + 19 in = 28.25 in
That's too small.
Factory tire is 255/55/19 = 1.1 times 255 + 19
which is 280.5mm + 19 in = 11.04 in + 19 = 30.04 in
You are limited to a minimum wheel size because of your brake rotors. I don't know what the limit is but it may be only 18 inches for an HSE or may be 19. That is the main reason I bought an SE and not an HSE. I don't know if the SE can use 17 inch wheels but I think it can't. You can be pretty certain though that you can't run 16 or 17 inchers on your HSE.
You could import a set of 17 inch wheels from europe...
Would probably cost a lot of money though.

In either case, it looks like I'm going to have to get dirty to measure the size of the rotor this weekend and see what clearances I have.
Followed the link by british_rover and the UK site has some weird acronyms that I'm not familiar with...
for the HSE, the rims are stated as:
"5 alloy wheels 19 inch ilo 18 inch style 2"
I would assume that "ilo" is "in lieu of"?
Does anyone know if there is a recommended minimum safe clearance between rotors and rims?
Thanks!

BFGoodrich All Terrain T/A KO (LT285/70R17 121Q)
BFGoodrich Krawler T/A KX (37X12.5R17 116)
They both have an "R17" at the end, which tells me they should work on a 17" rim - the KX also comes in a 20" size, but the sidewall is too tall.
Also found a Pirelli Scorpion ATR (265/70R17)
The outside diameter of these would be 31.6" - compared to the stock 19" rims with tire OD of 30.04
Would that be close enough?
Sounds right to me. ILO (I live online :shades:)
Means a tire with an unladen height of 37 inches and an unladen tread width of 12.5 inches. It is a Flotation tire measurment and is what was used for tires back before the P-Metric measuremnt system was invented.
That tire is way too large for the LR3.
I have no idea why rover does not put synchrones on the LR3 as well.
The only tires I've found that I like that will fit are the 265/60/18 Goodyear Wrangler Silent Armor which is 30.5 inches in diameter and the 255/60/18 General Grabber AT2 which is 30 inches in diameter, the same as the factory tire. Both are still back ordered indefinitely.
Here's my new plan:
I like the Nitto Terra Graplers but the only size I'd get is the 285/60/18 which is 31.4 inches in diameter. It's been reported that these fit and don't rub except under excessive big dips at high speeds with a fully loaded truck - not a situation that I couldn't avoid. But, the spare tire is a very tight fit. There are 2 problems with the fit of the spare, the diameter is too big and it would take a lot of shoving to get it in, maybe even de-airing the tire. Even though I carry a compressor, de-airing would not be my first choice because if I leave it de-aired, my tire pressure warning light will come on. Only choice would be to de-air it, put it in place, and air it up. The other problem is the width of the tire. It would hit the towing reciever. But I found a fix for that. There are 2 rubber bumpers above the spare that can be removed and the tire can move up another half inch or so - you do need to pad one of the spokes of the wheel so it doesn't hit the mechanism up there, or orient the tire carefully.
But here's my other idea: Buy 4 Nitto Terra Grapplers of the 285/60/18 size and one any brand spare of the 265/60/18 size (i.e the Goodrich Longtrail or the Goodyear Wrangler SRA) which are 30.5 inches in diameter. Then, if you need the spare, the difference will only be 0.9 inches in diameter when the Nittos are new, and will be even less as the Nittos wear down. Most likely this will work until I can get the flat fixed. The 30.5 inch tire should fit under as a spare and the flat Nitto would fit because it would be flat. Another choice for the spare is the 275/60/18 size though this is less common. The Michelin Pilot LTX, Bridgestone Dueler HT D684 and the Dunlop Grandtrek AT23 come in this size. Then the difference in diameters between the Nittos and the spare would only be 0.5 inches when the Nittos are new. It is 31 inches in diameeter and I think it would fit - I'm going to have my local tire store air up any 31 inch tire so I can try it in my spare tire carrier to see if it fits. Anybody out there got a 31 inch tire on a rim that they could try this? It doesn't need to be an 18 inch wheel, any size would work because we only care about the outside diameter fit.
Has anyone determined if a 17 inch Discovery wheel will fit on an 18 inch LR3? If so, that could be another option.
What do you think of this plan??
The rubber bumpers above the spare tire are actually 1.3 inches thick. With the bumpers removed, and the wheel spoke padded, there is about 1 1/2 inches of clearance between the factory tire and the trailer hitch receiver so the tire width will not be a problem.
Here's a question. If the traction control system kicks in, is there an indicator light on the dash that illuminates? I have a 28.9 inch diameter spare right now (it's a long story). I plan to put it on with the other 3 factory tires at 30 inches tomorrow and take it out on the highway to see if it causes any problems or lights to come on. If it is OK, we'll know that the different sizes don't cause a problem.

I drove up to about 65 MPH and saw no traction control light illuminate. I then turned a few tight circles in a parking lot with the smallest tire on the outside of the circle so it would have to turn even faster. The outside tire was probably on about a 50 foot circle and the inner on a 40 foot circle, so the outside tire turned 25 percent faster than the inner one. Still no light.
So it looks like there should be no problem running the larger Nittos and a smaller spare tire.
I traded in my almost new factory Goodyears, but was only able to trade in two. I kept two, and did not have the fifth because I had an unrepairable flat in it.
So I kept one as my spare and now have an extra one hanging around if anyone needs it. It should work ok as a spare even though it is smaller than the new tires because I tried out a spare that was smaller than the others and it didn't light any lights or kick in any traction controls even when I turned tight circles with the smaller one turning even faster.
Anyway, my extra tire is the factory Goodyear, 255/60/18, 6000 miles on it but no noticable wear, no cupping, and never repaired. I can measure the tread depth and photograph it if anyone is interested.
So I am interested.
Do you still have it?
That does not sound right to me, cupping is typically an alignment problem. Before I head back to the dealer this afternoon, can anyone confirm whether LR Dealers are giving any relief ($$) for the problem?
Yes, I still have it. I'll add my email to my profile to see if I can have you contact me directly, else I'll ask the host to help me figure out how to contact you, or you to me.
LR was providing partial relief for uneven rear tire wear last year. Rear wear/cupping was caused by factory alignment spec, which was subsequently revised.
Thanks,
David
Sparker 330 is planning to buy my tire but I'll let you know if the deal falls through.
My local tire guy contacted Goodyear. Goodyear provided a new set of tires with me paying the shop for installation ect. The replacement set help up for about 30K. Cupping, road noise, handling issues and ect..
Little Rock, AR, where I purchased the truck, Memphis and the New Orleans dealerships had nothing to add or offer.
One of the salesmen in Memphis kindly offered a suggestion of a Cooper Tire. I do not have the size handy but will gladly pull the info for anyone interested. The Cooper are fairing better than the Goodyear but I have to constantly monitor the pressure. On the front I am finding that even a 2 pound difference in pressure will effect the handling. I religiously rotate and service the car. I did find the bushing comment in a posting interesting. Rover has a serious engineering issue here.
I love this vehicle. I bought one of the early ones and have had only the usual recall issues that you would expect with a first model year car. The tire issue is very expensive and annoying.
Your replies are welcome.

I have 14,500 and tire wear on the rear. I dont think there is a noise issue. I am going to take it in on tues and ask for new tires. They chose the tires and the wear issue is not related to anything but the tires they OEM'd on the car and sold. I hope this issue gets solved over time and I'd like to hear if other tires (like the Syncrones)are better and its not just the vehicle??. Otherwise I love the car and so does everyone else who rides in it
I will look it up for you.
I am at 16,500 miles. My rear tires are worn much more than the front. Since there is such a disparity with the rear tires it has to be something with how the car settles, aligns or whatever (discussed on here ad nauseum!). I hope Land Rover develops a better solution. The LR3 is too great of a vehicle for this problem to be present and affecting so many. I do go off road a bit for some wildlife conservation work i do (once a week and longer trips three times a year). I wouldnt take an X3 X5 or anything else with me. Even with the tire issue this is the only vehicle that i can pick up a client in and handle some of the terrain and weather i am in year round.
LR still has to fix this problem however!
I wonder if anyone on this board has had experience (miles) with either the Nitto Grappler or Michelin Syncrhones. Those are the two suggested replacements.
