Stock Suspension, 19"x11" rear, would you run a 305/35 or a 305/30

[4g63T]

Made the mistake of running 305/30 when I first got the Supra , after a few days I couldn’t stand how the rear tires weee thinner than the fronts so I switched to 305/35 and it looks 100x better

I am getting the same wheels what front tires are you using? and what brand if you dont mind.

What’s causing the rubbing issue? Is it the height or springs? Also what are the wheel specs up front?

Front is 19x9.5 +23 offset.

Its the height of the car along with the increased tire size. I'm not rubbing on the springs themselves but the wheel well liner. Springs were supposedly Eibach Euro Z4 spec for 0.8" but I could swear they dropped more than that. Didn't measure though. Effectively on full compression the top/inside of the tire rubs the wheel well. So moving rear out 3mm probably will work as the wheel well going on memory is still rising away from the tire ever slow slightly at that area so moving out gives a little more space above the tire hopefully avoiding any rubbing. Haven't looked into the front yet as its been pretty much negligible when I did rub...no real concerns on the front.

305/35 has almost no availibility... Especially in the 200TW category

Just drop down and accept the 295/35

If I were to do it again I would go 265/35 and 295/35 which would be great because it would likely solve any rubbing but more importantly I would have not had to go with Michelin PSS and could have instead got the PS4s or continental. Ordered the 305s because I planned to move the stock 275s to the front...turned out stock rear tires I had eaten up more than I thought so I decided to replace those too and wanted to match the rears. Oh well.

Hey did you ever try the 3mm spacer or did you resolve it? I’m running the same exact suspension and rear wheel specs and have the same issue under compression (going over bumps)

I'm intrigued by many who want more meat with a 35 i guess its preferred with a 19".
Here's 305/30 on 20x11 no rubbing, 275/30 front on 20x10 no spacers or rubbing... and let
me emphasize: Alb, NM might just have the worst Streets! Not enough of our Taxpayers $
goes to roads/highways. If i have a passenger in the car, the rear still doesn't rub.

Meant to do it this last weekend but was lazy. Decent odds I take care of this next weekend, regardless I'll report back when I have. I'm not super optimistic it is going to fix the issue or I wouldn't be procrastinating..

Sounds good. Take some pictures of any possible wear areas if you can. Going to try and remove the wheel and see if I can find the cause (don’t think it’s from the fender/qp)

Overdue but said I'd update - I did put 5mm spacers on a while back and this did not fix the rubbing on compression. Rubbing is inner top wheel well - noticeable on the liner but visually didn't see any impact to the tire. The reality is I seem to need to be 5-10mm higher in the rear with the 305/35/19s. For now I'm just ignoring and coilovers are at the top of the list next time I have 4 grand burning a hole in my pocket.
