From the old vets on this forum just wondering how
The guys made out or still making out by putting the 305s on your stock wheels?? Not tryna bring up this old debate but a lot of guys did it and loved it. Just wanna make sure it held up until now before I do it.

Its definitely debatable, as the bigger size does not always mean better traction. I am no expert but understand that the contact patch changes with width. It would be interesting to hear what everyone's experience is with that set up. Could have some pros, could have some cons.

Check out @pt1less on instagram. He's running a super wide tire size on the 1LE rims, I think like 325s lol, had to do the driver side wire mod but that's literally a 5 minute job. In my experience a warm pilot sport tire/P zeros for 305s grips great.

305's on a stock 9.5 inch wheel is pointless and will bulge out. If you want a 305 size tire, the wheel should be no less than 10.5.

True but its. A LOT of guys that did it I need them to chime in from the 2016 SS. It looked GREAT

I assume this refers to stock SS wheels?
Pictures with size details would be great if anyone can post them up.
I’m interested in moving away from the stock GY, but haven’t saved up enough for the move to Z28 replicas yet. 😉

30-profile tires aren't supposed to have a rounded sidewall shape like you might find on a truck riding on 70-profile rubber. To anybody who knows much about tires, it looks like one of two things . . . either being too cheap to buy wheels of the right width for the tires or trying to fool people who know even less about wheels & tires than they do.

The only exception is certain autocross classes where you are allowed to go wider than stock with the tire size but the wheel width is limited to stock. Not a good setup to DD on.


I'd be uneasy about putting 305/30's on 10.5's, and even 11's are none too wide. But if I'm buying 305/30's at all, it's going to be for cornering feel and potential.

Are you saying you wouldn't run the stock SS 1LE wheel/tire combo?

Specifically about the 305/30's, I'd run them on 11's if that's what I already had to put them on. But if I didn't have 11's to begin with - if, say I was starting with a non-1LE SS (or even the car in my sig in the days before it got the set of 11's it's pictured with) - I'd start my wheel search with 11.5's.

As for 305/30's on 10.5's, let's just say I've never been a fan of running tires on wheels of min-recommended width. Just so you know, "never" reaches back almost to the very beginning of the 2nd gen F-body . . .
