Hibiscus Red S4

I've decided on this tire, and was wondering what size I should use. I'll be using stock Avus 7.5 x 17 inch rims. I'd like to go a bit wider if possible (235/40/17 or 245/40/17). I have stock suspension now and don't want to roll fenders or use spacers. I am considering STaSIS Street Sport Coilovers for this spring or summer and want these tires to have no rubbing issues. Best thing to do?

Here's a list of tire sizes and acceptable rim width measurements (specifically for the ST-115)

225/45/17 - 7"-8.5"
235/40/17 - 8"-9.5"
235/45/17 - 7.5"-9"
245/40/17 - 8"-9.5"

I think you can get by with 235's. Check tire calculator conversions on the internet.

I guess I'll be going with 225/45/17 or 235/45/17

I wonder if the 235's would just have more sidewall flex though?

Sidewall will be 0.2" taller. Your speedometer will read 1.4% too slow.. just under 1 mph difference at 60 mph.

i have these tires in 225/45/17 on my OEM 17s, are run really narrow. I'd go with 235s.

Alright, thanks for the heads up! How do you like them? What can you compare them to?
