Front Tires Help!!
Hey guys, I have a 2012 Competition pack and I need new front tires. I’m running 255/35/19 up front and 295/30/19 rear both on Pilot Sport 4s. I want to bump up the fronts to 275 but I’d have to drop to a 30 sidewall instead of 35 but I’ve had people tell me that’s a bad idea. Idk too much about sidewalls so could someone explain to me why it’s a bad idea or why it would be ok. Also I’m doing a track day soon if that helps with context at all. Also if it’s a bad idea, would 265 be the most I could go while keeping a 35 sidewall?

Well the front rim is 9” wide and stock is a 245 tire. You are adding more than an inch to the tire width with a 275. Just doesn’t seem like a great idea from a wheel/tire width perspective. Ignoring the sidewall question altogether.

the middle number of a tire size is the aspect ratio of width to sidewall height. the overall diameter difference between a 255/35 and a 275/30 is about .4". in the context of radius, it's even less of a difference. so, is a wider tire more beneficial than a tire with more sidewall? might be debatable. my 275/30/19's fill out my front competition wheels great, but i'm not tracking on them, so it is difficult to give advice with that application in mind. i think i would value more tire over more sidewall though.
