Default wheel/tire combo for autox

I am currently running the stock 16" with Victoracers 700. Was wondering if it would be better to get a wider wheel and tire combo. What type of wheels and tires are you guys running?

You need to tell us what class you plan to run. If you want to stay in stock class, then you'll have to stick with the stock wheels. Wider wheels will put you into a different class that will require additional mods to be competitive.

Stock wheels with Kumho V710's (225f / 265r) or Hoosiers (225f / 245r) seem to be the hot setups for stock class.

So there's lots of possibilities, then! I'd stick with the V710 and Hoosier A3S05 as top notch tires, but you want something wider than stock.

245 / 275?

I'm thinking of getting the V710 next and would like to run 245/275. However, I'm unsure which wheel would work with this size.

Start surfing for wheel specs:

17 x 8 fronts (45 - 50mm offset?)
17 x 9 rears (50 - 60mm offset?)

Do some math and figure out the offsets you need. I know SSR makes the Competition and Competition H in those sizes. Just search and make a list of wheels that might fit and their specs. Something will jump out at you as the "right" wheel.

To measure for offset, measure the clearance (perpendicular to the hub) from the face of hub to the closest inside obsruction. Or better yet, measure the clearance from your current tire to the nearest inboard obstruction. Also measure to the fender lip if your springs are soft enough to allow you to rub the tire on the fender.

When you widen wheels keeping the same offset, half of the extra width goes on each side of the wheel centerline (and each side of the hub face.) If you add one inch of wheel width and keep the same offset, the outside edges of the wheel will move out half an inch in each direction.

Reducing the offset of the wheel will buy you more clearance to the suspension components (control arms, shock or spring, etc.). Increasing the offset of the wheel will buy you more clearance to the fender lip.
