15x7 Rota RB with.....

Post by Thomcraft »

Been beat to death I know, but......anybody out there running 185/60-15 on a 15x7 +12.
I'm replacing 175/75-14 that came on the car and my speedo is very accurate with that size. Changing to a 15" wheel requires a 185/60-15 or 195/60-15 to keep tire dia the same. Just don't know if +12 offset on a 15x7 wheel with those tires will rub. Anybody? :oops:

In my experience the 195/60 will rub in the front at the fender lip.

HA!...dueling threads.
Just trying to keep tire dia the same for the sake of my speedo and I like how my current 175/75-14 fill the well. The offset must be the issue.
Thanks James.

No - it's the extra 20mm I think on the width. I'm not sure what the offset is on the stock wheels - does anybody know?

Cheers

Online tire calculator says 185 tread too small for 7"wheel, recommends 5-6.5" wheel.
Also creepy thing is my tires on the car now, (175/75-14) are not even recognized or available at any of major tire stores ie; Discount tire, Tirerack, Lester Schwabster. Wierd

I have 195/50 15 tires on a non lowered car. They fit the front fine.
The rears might need some working.

My rears are not stock and still need some additional working to get 205/50 15 to clear.

I tried the 195/50 on the rear before the "work" and they would still need some working......
I would assume 195/60 would be worse for fit.

i think you will be fine if the car is on stock springs, it's ok to run the 185/60/15 tire, it's a relatively large sidewall in that size.
