    Sbcooke,

    I'm assuming the 4runner you guys have is the Hilux based vehicle which has been around for a long time now. If that's the case, then the current Prado we have in Australia has more room than the 4runner and approaches the Trooper for capacity. The seating in Trooper is roomier and more comfortable than Prado. Prado has more rearward travel in the front seats though.

    Also, Prado's 3rd row seating is for 3 persons (skinny, little persons) so it is an 8 seater. The seats also fold up more efficiently than the Jackaroo's, taking up less load space.

    I can't comment on the new generation. I haven't seen it other than on the net.

    The only Lexus SUV we have is the Landcruiser based LX470.

    My wife just called me. It sounds like Monty's transmission has had enough and is now clunking and jumping badly when selecting Drive and when shifting gears.

    It's off to the dealers under warranty, probably under tow.

    CKnott,

    Just making sure I read it right. Your mileage deteriorated with the larger diameter tires?

    You would expect that the larger circumference of the tire hence the fewer revolutions per mile would mean less fuel used.

    It would seem that the gearing change means higher fuel consumption instead.

    It's the un-sprung weight and energy needed to get the heavy tires moving. Also in my case the 275-70s have about 30mm more tread on the ground so more rolling friction. Also you need to punch it more to get up to the same speed.

  • So Paisan what did you think of Paragon? Was it worth it? Would you do it again?
  • paisanpaisan Posts: 21,181
    It was excellent. I had been there as a passenger once before. Definitely will be heading back again.

    Is there any tire out there that was designed to be more efficient in a larger size, particularily larger but made with lighter materials that are still strong?

    Tire weight is usually not even an available parameter in tire data. It should be one of the important data they compete on.
  • paisanpaisan Posts: 21,181
    My guess is no. Unless you go to a narrower tire you likely will be stuck with a heavier tire, especially an LT tire. Tire weight is usually listed on the manufact. page. I know it's a big issue on my subaru when buying race tires.

  • it's not so much the weight/mass of the tire, it's that when you increase the radius a small amount, you are increasing the polar moment of inertia a large amount(which directly increases the amount of energy stored in the wheel at any given speed). Now if tire and rim manufactures posted the roational inertia numbers for their tires, that might be something. There are some easy tests to figure it out, but they require actually having a wheel/rim in your possession :-( The total mass/weight of the tire does contribute to how hard it is to get rolling, but if I had a 100 pound bowling ball, and a 100 pound 32 inch tire, I'd rather try and roll the bowling ball :-)

    Why are tires not made with kevlar belts instead of steel belts. Kevlar is what bullet proof vests are made of and it would save a whole lot of roational inertia. I think bike tires are made with Kevlar. I would be willing to pay 50% to 100% more for lighter tires because they would pay me back in performance and MPG.
  • that is a good question. I wonder why I haven't seen any kevlar tires for cars. I have some on my bike though. Kevlar is alot mor expensive than steel. Kevlar can stop a bullet, but sharp fragments that don't compress will easily cut through it (ice pick, non-hollow point bullets, knives...nails, glass...). Oh yeah, and larger tires can almost be guaranteed to hurt your city mileage, sometimes they will increase your highway mileage though. I wonder if kevlar can stand up to the temperatures of car tires and those loads.

    That audio clip of the radio guys scamming the girl is hilarious! I feel like I'm going through the same thing with the Subaru dealer. Actually the costs did go up to about $1200.00 but it's because I'm electively doing a few extra things. Essentially, parts of the 90k tune a little early. But, I decided to get a little leverage against the dealer and sent out 9 faxes to local shops using the list of parts the dealer faxed me. I'll see if there's any arguement that cn be made for labor (primarily) based on any trend I see from the independent shops. Will keep you updated, and no, you can't buy it as is. :)

    Bridgestone Dueler R/T is a kevlar belted tire that is used by the Holden Rally Team. So it suits the Trooper/Jackaroo. However, big $$$ in Oz! Something like $700AU each!

    I agree that weight should be a parameter that is specified in tire catalogues. I sometimes wonder how much those BFG A/T's are costing me in fuel, as they were fitted prior to delivery of the car. So I have no experience with the standard Goodyear Wrangler AP's.

    Guys,

    My transmission woes were fixed for now quite easily. It was a management module glitch. Error P0705 - Transmission Range Finder. Basically, the car is female and was having a blonde morning being unable to decide what gear to use.

    If your gear changes are accompanied with banging and shuddering, stop immediately, turn the car off and wait a minute. Start up again and the symptoms should disappear. Proceed to your dealer ASAP and have them check the computer diagnostics. They will see how often the problem occured, reset the management module, give you two aspirin and send you on your way.

    Make sure that you keep a record of events, because if you get a repeat you have a real problem, not just a glitch.

    Mine is going back in a couple of weeks for a further check of the diags and to see if the error has reoccured.

    When my brake lights blew a fuse, my tranny acted exactly the same way. I popped in a fuse all better.

    I can see the relationship between a brake light fuse and the transmission .... NOT!!!
  • paisanpaisan Posts: 21,181
    Basically if your tranny starts acting funny you are gonna get the car checked out. They do this often as "attention" getters perhaps? It worked for me though.

    I am deciding between 275/70 and 265/70's. What concerns me about the 275's is airing down. When I go surf fishing, you have to air down to 12-15 PSI for optimal traction and not to destroy the beach. With the larger tires on the stock rims, I am concerned about them not being able to stay on the rims at such low pressure. Any thoughts?
