Subaru Legacy/Outback Tire Issues

    My concern would be the front tires rubbing at full steering lock. Take some measurements.

    60 to 65 series is not that big a change, though.

    I would read your owners manual. Outbacks need there tires rotated every 7-10 k miles . You will destroy the awd system if the tires are of difference sizes.
    Hope you have not already done damage to it .

    We finally decided to go with the Kumho Solus. However, we chose the HP4 tread design as opposed to the "touring" tread design. The tires are on their way to the installer, so hopefully we will have them on next week some time.

    There is a lot of positive buzz around Kumho tires, so we are giving them a shot.

    The only ones I've liked are the VictorRacer Race tires. When the WRX came out people were using their street tires and I can't tell you how many bubbles there were in them after short periods of time :(

    As long as all four are bigger, that shouldn't have an effect, i.e. do not buy two bigger tires, buy a set of four. Better yet, 5 with the spare.

    No, think the intent of the previous post was to say that by not rotating, the tires are likely to wear at different rates (for example, front wearing faster than rear). As a result, this could lead to sufficient differences in circumference to cause undue stress on the AWD system.

    I think it would be tough to get enough circumference differential to cause damage to the system simply through not rotating the tires, but I guess it all depends on how aggressively the vehicle is driven. Considering the RE92's have made it 50,000 miles (!), my guess is that the vehicle is not driven aggresively. ;)

    The space is tight though. Intuitively, I would surmise the increase you are seeking should work. I doubt the height gain will be noticable though. You might do better to put a 2 or 3" lift on it (if such a kit is available).

    I always thought tire wear on an AWD was relatively even. Power starts and other such actions would wear the driven tire of a FWD and RWD but with an AWD they're all driven so the wear is even.
  • My 2003 Outback with the 225/60 16's that were never rotated is a manual tranny which gives a 50 - 50 front to rear traction drive. I understand this is a different system than the auto which is like 90 front to 10 back. That may explain the mostly even tire wear. Most of my driving is around town which may explain the 50,000 miles. I wrote subaru about putting on 225/65 16's and also about ways to raise the body or suspension, however they just say they do not recommend making any modifications (to protect themselves I guess). The wheel wells look like they may have 1" of clearance at best and when the front wheel is turned to the limit as one person said the clearance is quite tight. I am beginning to think that it may not be worth the gamble to try the larger tires. I may just have to go back to an SUV or truck that is more suitable for offroad. I just hate to give up all the other advantages to the Subby.

    Thanks again..............

    It does wear evenly, in fact I have trouble keeping rack of when I did the last rotation because there is no visual clue.

  • Why not try plus zero of 235/60-16? Wider tire, with a bit radius, and less than the 225/65-16.
  • ateixeiraateixeira Posts: 72,587
    Not a bad idea. 10mm wider where you contact the sand, too.

    That's what I did with my Forester - went from 215/60R16 to 225/60R16.

    Hard cornering will still wear the front tires faster. I had not even considered the drive (AWD/FWD/RWD) factor, but that could be significant if you make a habit of burning rubber. :D
  • ateixeiraateixeira Posts: 72,587
    My OE tires did that, but my 2nd set did not, nor did my 3rd set. Maybe I slowed down a bit since I usually have kids in the car. ;)

  • Hey Juice,

    Can you state what were real world differences in mpg, handle and power with the Forester?
  • Follow up on advice:

    Concerning fitting 235s on the stock wheels, according to Discount Tire Direct, the stock wheels can only accomodate 225 as its widest, so unless a purchase of new rims is in order, my original advice of going to 235 is not feasible.

    Too bad, cause I was headed that way as well.

    Rather than spend so much effort in trying to fit a different size tire on your car, may I suggest a different approach? I think what you are really looking for is a tread pattern for sand or snow that grips and moves the vehicle forward, rather than spinning and effectively 'digging' the vehicle in with each revolution.

    I would suggest that you visit your local tire stores with a flexible tape measure in hand. Look for an open tread design with lots of bars across the tread rather than the more typical bands. Also check the circumference. Tire sizing is somewhat variable. Winter and Off-Road tires typically have 10-12 / 32 tread depth rather than Summer and All-Seasons, with 8/32 or so and thus stand taller.

    Shoulder broadness also impacts actual tread width on the road. 235mm is the section width measured at the widest part, the tire body center. Actual "tread width" can vary all over the place - maybe up to an inch depending on the tire model.

    I first went from 205/70R15 to 225/60R16, with new rims as well. So that change was dramatic, as you might imagine.

    But when those tires were worn, I went from 225/60R16 to 215/60R16, which is the stock size. I downsized because I no longer drive on the beach. We stopped going to the Outer Banks and I own a place in Ocean City within walking distance to the ocean, so I no longer needed the wider tires.

    To be honest, the differences were small. The new tires are Falkens and I like them better, but I attribute that to the tires themselves being better than the Nitto NT460s I had on there before.

    Thank you Doug, that is exactly what I want to do. All I have to do now is find a set of rims, and then replace the silly tires that came with it.
  • Tire width has very little to do with load rating (handling the weight). Wider tires are more likely to float over water (hydroplane) and have less snow traction, but are also more likely to float over dirt and sand. The OEM tire and any replacement should be rated to handle the max laden weight (GVWR) of the vehicle.
    What is your goal of changing to a smaller diameter tire? All that would do is increase the sidewall height which will decrease the handling on road and make it harder for the tire to support weight.
  • I have had VictorRacers and Ecsta 7## as well as Ecsta ASXs currently. So far I have had a very positive experience with all of them.
