holy crap:oops: what`s the back space of your wheels? any more than 6.40 to 6.50 backspace your rubbing bad. both my 18 an 15 inch wheels are 6.37 inch backspace. my 305-45-18 required nothing, my 315-60-15s needed the hammer cause tires are so tall. 18s far left banded 15s on right

The wheel likely matters a lot. You guys need to list your wheels when comparing what fits and how.

I'm curious if a 315 would work on my Weld 17x10s. I need to go look up BS.

My Welds are 6.7BS and 30mm offset.

just looked up your wheel specs, your backspace is 6.68 inches.
mine are 6.37 inches, the inboard bead on your wheel is just over a quarter inch closer to sheet metal than mine an the taller the tire the worst it gets were the metal curves at the frt of wheel well.

@Hpindy can tell you what his back space is for comparison but looks like your back space is the same as fumanchu

By the look of it your rims might have too much offset .

That's more then what I did ..... But I'm running poverty stars at the moment. 17 X 9.5
6.125 back spacing with a 22.5 offset

your wheels are much better suited for 315s.
the least amount of back space = more inboard clearance
the taller the tire = the least amount of clearance were the tread meets the sidewall.

As much as I dislike these wheels they do fit pretty good with the 315's .

The DA should be way better unfortunately the baro will be lower than I would like to see this time of year.
Hopefully the rain pisses of so we can get it done. I doubt there will be any other chances this year.
