have a set of the titan 20x9.5 +30 wheels coming in for the front of the rcf. What’s the widest tire somebody has been able to stuff under the fenders without rubbing? Car is currently on Penske coil overs with half inch drop. Will be running pilot sport cup 2 on these wheels. Hoping to get at least 275/35 in there. Don’t have wheels yet so can’t do my own measurements and running short on time for next event. Thank you in advance for all input.
Katrcf - I would go with 275/30 on the 20x9.5 for max tire width on that size rim... 35 will be too tall and rub the fender liner on that setup. From my measurements you could go with a 20x10.5 or 19x10.5 45mm offset and fit a 295/30 up front for a real max width on stock fenders.
I'm doing a square setup myself with 295/30s, but sticking with 19x10 41mm offset to keep the diameter at 26", give the rims some protection, and keep stock fenders unmolested. Wheels are here, gotta do new powder coat next, then tires and go on for me.
I’ve ran both size tires on a +35 rim with a modest drop.
275/30 good to go.
35 series will rub.
cups don’t come in 275/30 though. FYI.
Really curious if 295 will clear if the car is lowered some. May be +10 mm offset will get you there.
Heard Pete/red devil rcf is running square 295. I’m skeptical.
Personally have tried mounting 295/30 on my rims. Didn’t even come close to clearing. Would rub at full lock standing still without any compression.

Thank you all for the input. Since I still don’t have the new wheels yet, I’m ordering a replacement set of factory size fronts for this weekend racing. Once I have the wheels, I’ll be able to measure to get the right size. Got some 305/30 for the new rear, so hoping to squeeze a 295 on the new front. Would go 275 but sc2 doesn’t offer that size in a 20.
Will update and post pix when I get the front figured out.

if you're sticking with 9.5 in the specs you listed earlier up front don't bother with the 295...
Biggest front rubber?
Holy Smokes!
