Post AutoX tire wear; input?

Compound is more important than size. Competitive tires don’t leave the user with many appropriate size choices.

For comparison, 275 40 is so so so so easy to mount I know wish they came in 285 35 as you suggest.

Your wish is granted.

WTH, BF Goodrich has stopped making Mustang appropriate sizes of the Rivals again?

What are Mustang appropriate sizes ? Only one they had for F Street was 275/35R19 and it was introduced last year if I recall correctly - and it came with together with 305/30R19.
Talking about Rival S 1.5 - previous version of it never had Mustang sizes.

It’s VERY hard to mount a 285 35 re71r on a 9 inch wide wheel and get it to hold air. I saw a whole circus of professionals and amateurs fail. Other brands might be more forgiving but I haven’t tried.

RE71Rs are tough on the tire guys.

The 305/30R19s were actually harder to seat on the 11" wheel and get it to hold air. The trick was shaving the little casting nubbins off the bead area with a razor blade. I do that now before I drop off the tires for mounting after waiting an hour plus for one set.

I dropped off a set of 285/35 RE71R at the local tire place for mounting on my stock 9/9.5 staggered PP1 wheels and they were like 'ok see you in 20 minutes'. I just laughed and came back 45 minutes later and they were still struggling, having worked on it the entire time I was gone.

Definitely getting my money's worth from the tire guys. They're easier to dismount/mount when they're worn down, but the new tires are pretty stiff.

@NightmareMoon i did mean 285 30 R18 Re71R (Yep, I modified the offset of some wheels on a Bridgeport)

If you cook them in an oven at 80C for 15 minutes, they get softer and easier to play with.

Must be a big oven!

Sizes that are reasonably close to stock diameter, and wide enough to be useful.

They were making a 285/35-19 at one point.
It would be nice if someone would make a good 295/35 & 305/35.
Yes 305/30 works but it's a bit short. 295/30 is too short.

Wasn't that original Rival (without S) ? Last five years I don't remember usable BFG in a stock F-Streetish size for 19" wheels.

305/30 works pretty well on 18+ cars (~72mph max in second, could probably go shorter although bunch of times this year I was on limiter) - at this point they were being made for just as many years as 15-17...
