Is this possible with no downsides?

I had a blowout yesterday two states away and these were all they had in stock. I went ahead got them (Potenza S02 PP's) and got the 245's in the front. I replaced the S03's, which I've had 2 fall apart on me in less than a month. I've read that the S02's are still better than the S03's, as the S03's treadwalls just fall apart for some reason?

The left side does not rub, but the right one does slightly when I go over large bridges, bumps, etc..

Could this mean that shock is work out? I'm going get some new KBYAGX's sometime soon...Also get it remounted/rebalanced...Thanks..

1) 295 is insane on a 9" rim. If that's all they had in stock, then good, they just loaned you some free tires while they can get some properly sized tires in stock. Get some 255s or 265s. Any particular reason why you downgraded from the stock wheels and got 9" wide wheels in back in the first place? Stockers are 9.5" wide with a 255. Why would you think you can safely or properly put a 295 on a narrower 9" wheel?

2) It's not the shocks, a 295 will rub on the fenders on either one side or both unless you have the PERFECT offset (Steve Jarvis knows what this offset is; I don't). Back when I had OZ Competition wheels (17x10 with I believe a 41mm offset), I had 275/40-17's on them and only the right wheel would rub. It appears that on a lot of Supras if your tires are just barely not going to fit, the right rear will rub before hte left rear.

Andi,

Thanks for replieing. When I purchased the car, The rims came with it. These were the only tires they had in stock, I didn't have much of a choice. I wasn't going to drive 12 hours on that donut with no tread, hehe...

So if I talk to Steve and get the "perfect" offset, then they won't rub? Thanks..

That is correct, you can fit a 295 in the stock fenders w/o rubbing if you get the wheels Steve Jarvis had (18x10.5 with "the perfect offset", although I don't recall what that offset is).

Steve has a +55 mm offset rear. I think Yasir also runs 295s on his car... I "think" his are +58 mm offset. They both have 10.5" rear wheels. They both have gorgeous wheels too...!! ******** and Kinesis.

I am jealous.

I've read about some guys running 315's on the rear of their Supras. What size wheels do you need, and can you get these on without have to do fenderwell work? Those would look nasty!!

 

[fiore36]

i plan on running 315s on my rear, but i will also have an 11" rim. i will be going with Fikse FM5. i think someone on here has them. i am going to have the fenders rolled when i get my dent fixed, just for extra insurance. but supposedly if you can get the backspacing just perfect you can make it fit without worrying.

 

[powersoundsupra]

Maybe we can get Steve to tell us what offsets we need for all the different sizes.

example:

What offset is needed for an 11" rim with 315's, 310's,305's etc.?
What offset is needed for a 10.5" rim with 295's, 275's, etc.?


A little help Steve......


Greatly appreciated

To run a 295/30 on an 18x10.5" wheel you will need a 54-57mm offset. I have a 55mm offset and Yasir runs a 57mm offset. I would recommend a 55mm offset if you can get it. For a 305-315 on an 18x11", you will need to roll your fender lip. I would run a 50-52mm offset for a 305 and a 45-47mm offset for a 315. Andi should be able to give you some better information on the 315 fitment.

My 17x11s with 315s are 47mm offset according to The Wheel Source. My 17x9.5 fronts with 275s are 43mm.

thanks randychunn

You do have to modify the rear fender lips to get 315s to fit, yes.

Yes, Andi does have rolled fenders.
