Can I run 295/30 tire (thread width 298mm) on a r18x10.5 wheel with around -3.2 camber and ~10mm lower than stock in front with no spacers or it wont fit/will rub bad?

what offset? What suspension?

Ohlins R&T. Offset anything from +25 to +50 can be custom made. Was thinking 18x10.5 +25.

+25 would be pretty aggressive.

Last year I ran 295/30/18 Conti ECF's on 18x10.5 +35 all around with zero issues.

This year I ran 295/35/18 CRS V2 which are about 305mm wide on 18x10.5 +35 with zero clearance issues.

I mean I can specify wheels to be +30, just want them to fit/not rub, so isnt lower offset "safer" ?

Im on 18x11s with a 37 offset and no rubbing unless im at full turning lock. They are pretty close to rubbing the springs though. Dont think I would want to push the wheels out any further.

Well, is there any downside going lower offset? Why not push the wheels out bit more ?

Then you're stuck with that offset. If you go with a higher offset you can always run spacers.

Rubbing on fender lip/liner

I dont care, all i want for track wheel is to fit good, I wont change offset anyway.

Rubbing on fender lip/liner

Ah ok. So I should run as high offset as possible to clear brake caliper but not rub fender liner?

10.5" wheels arent hard to fit up front. 35 offset has been proven to fit many times so thats the route I would go. If you can get a 40 offset, then get 5mm spacers to go with them. 30 offset is just pushing it.

It's a balance between clearing the strut/spring and not contacting the outer fender.

Like @Evolution stated, +35 is a good known fitment with MK5 Supras on coilovers.

The 295/30/18 isn't a hard tire to fit honestly. Here is a 295/30/18 Conti ECF on 18x10.5 +35:

Is that on coilovers? Was thinking about exactly same setup.

I debated which offset to go with on my Apex 18x10s. I decided on 10" ET 30s as opposed to most of the wider set-ups here. I am staying with the OEM struts and springs. I want to run the particularly wide CRSs 275/35s. I do have plates and close to -3.0 up front so I am hoping I will not rub fender or spring perch. I guess we will see.

Am I the only one who runs/has run rt660s?

I just picked up a set of Titan 7's with these tires, looking forward to trying them out this Spring
