245/xx/17 Tire - 40 or 45 series?

[kickasskid2087]

Have a 97 tsi awd. Lowered on Koni/ground control. 700f/400r spring rates. Fenders to be rolled. Wheels are 17x9 +25. Run a 40 or 45 series 245? 40 series is 0.6% shorter than stock. 45 is 2.6% taller than stock? Which would you run and why?

Thanks, Alex.d

40... when i was running evo 8 wheels i ran 45 profile tires and had rubbing issues solely due to that fact (had been running 245/40/17 previously)

Yep. 245/40/17 is my favorite street tire for a 2G.

 

[kickasskid2087]

May I ask why exactly^^^^

 

[jtmcinder]

Widest that will tuck in the rear without much work. And back when I had a 2G, it was a size that included my favorite street tire: the old Kumho MX.

Plus, the 245/45/17 is too tall. You're giving up too much torque.

Thank you!

45 profile is too much. I run 255/40/17's and my car is lowered quite a bit also and it looks very nice, with no rubbing.

I'm running 245/40-17 Dunlop sport maxx TT on EVO 9 wheels on a '99 GSX. It's lowered more than I thought. The back tires just barely kiss the fenders on a really bad bump.

 

[jtmcinder]

Evo 9s have a +38 offset, which is almost perfect. A good rolling of the rear fender lips should take care of it.

I'm running 235 tires that are the same width as 245's. I'm running a 45 sidewall and I love the way the car feels with this setup. I'm not lowered, but if I was planning on lowering I would probably go with the 40s so you have more room "just in case."

Cheers.

Edit- I should also add that I'm running a 17" wheel with a +38 offset (Evo 8 wheels).

245/45/17's with a +25 offset might put you close to rubbing on the rear knuckle. If so it would be an easy fix with some wheel spacers.

If your going for saving some gas the taller tire would help. Save gas....

My vote is for the 40's.

Actually, +25 would move the rim further away from the knuckle.

Your right. I had stayed up after working midnights trying to get set back to day shift. My bad.
