Anyone know the correct size hoosiers for a 2016 clubsport with stock wheels?

Thank you!

From the factory the GT4 CS comes with 9x18 and 10.5 x 18 wheels....Pirelli tires were 265/645-18 front and 305/680-18
These Pirellis do run a bit narrower than the spec and I have been able to use 275 upfront (19x9 wheel) and a 265 Hoosier works on 19".
On the rear 305 should be the max but I have heard people using 315 Hoosiers in 19x11" wheels.
Max aspect ration on 18" Hoosier at Tirerack is 40...Not much choices.....the best combo IMO would be 245-40 18 up front (next size is 275 not sure on fitment) and 295/40-18...unless you want to try the 315 but at 10.5" on the rear wheel that will be a tight fit.
Maybe actual GT4CS owners can chime in on this with more data.

Thank you! I'll get the more conservative size and report back. I've got a set of new Michelin slicks for Sebring next weekend, so could be interesting to compare!

No problem either the Michelin or Pirellis will be better than the R7s
The Pirellis seam to be more expensive than the Michelin.
Below you have a little chart I made for comparing diameters and section width...mostly for comparing 20 vs 19" but I do have the CS Pirellis in there. You want to stay as close to OEM measurements as possible.

the suspension that comes with the Clubsport is not setup for hoosiers.... If you just want to puddle around it doesnt matter but if you want to go fast , or learn to go fast it or learn to race it actually matters.

That's true...these car were delivered with slicks. Never the less, I think it could be setup to run on any tire you will however be slower and will have to try various setups (R&D) to make it work at the lower grip level.
