Anyone here have experience running Toyo R888R 305/30/19 on their Supra on the rear? These would be going on Gram Lights 57CR 19x10.5. I’ve read numerous threads on here, and have seen some set ups running 305s, but they have been other tires such as 4S and Sport Cups 2. The R888R run pretty wide for their measurements and I would love to avoid rubbing.

I think the 305s are gonna rub. 295 is pretty solid without rubbing. Let me know if you want pricing on Toyo's!

You have my email. ;)

So the r888r 305/30/19 are a perfect fit. No rubbing. It’s actually the 265/35/19 up front that have some minor rubbing. There is a small tab on the fender that the sidewall rubs against when the spring is compressed under load. More negative camber will fix that though. Camber plates on the way!

What studs and lugs are you running?
I’m running a 14x1.25 to 14x1.5 wheel stud conversion from motorsports hardware. They’re the 78mm length ones. I’m am using spoon racing lug nuts. They’re pretty much just regular hex lug nuts. They use a 19mm socket.

What is your offset on rear wheels?

Can confirm that 305/30/19 Toyo Proxes R888R does not rub whatsoever. Also lowered on Eibach springs.

It would help if we had the offset and width of the wheels. That will play just as big of a role with rubbing. If the tire is 305 wide and the offset pushes the wheel out, then it would rub. If we had a 315 and change the offset to go in 10mm, then it would not rub on the outside. See what I mean? I'd like to get 20x10's on the front, I just don't know the offset, tire width, and wheel design that would also clear the brake calipers. In the past, with deep concave, my wheel would get stuck on the caliper and I would need spacers, throwing thing off again.
