RS-3 V1, RSR, and now RSRR. I suppose both these brands run a bit wide.

Yep they do thats why I was curious. Thanks!

I ran MPSS 245/40/17 on 17x8 wheels and they fit perfect. I wouldn't go anywhere below 245 on 9" wheels unless a specific tire is well known for running wide.

It really depends on the tire. These are 235/45/17 Federal FZ201s on 17x9 57CRs. They run really large and measure out to almost a 250.

I have 17x9s with mpss 245/40/r17s. Tire fit the rims well, but I did need spacers up front to prevent rubbing on the suspension. Love the setup, noticeably better grip.

What rims & suspension are you running?

I pick up my MPSS 245/40/17 on Saturday on the Rota Titan 17/9 E42 and hope I don't need my 5mm spacers? Guess I find out soon enough

Are you on 17 × 9 rims now?

The PS4 has ever so slight stretch to the sidewall but not much but I'm more than happy and very impressed with these tyres (tires ).

PS4 's are currently available in 18, 19 or 20" here in the states

Naa.. still on the stockies.. running federal 595 in 225/45 17. These are my fall /winter tires.
the 17x9 setup will be for summer, most likely with the continental ECS.

That ended up being a waste of time, Costco would not install the tires as I would have needed my spacer to clear the front strut. They did refund my purchase in full

Trying to decide on the Continental extreme contact sports.

which would work better on a 17x9 wheel?

245/40 or 255/40?

245. Don't see a point in running 255 unless you're trying to maximize grip in competition.

That's bs because I ran 17x9 +42 et up front with 245/40/17 for several years without any rubbing.

Maybe you already have negative camber up front via camber bolts though, that would cause the tire to be closer to the spring perch.

Michelin run wider than some tires. I know the AS3+ was almost an inch wider than the Pirelli P Zero AS tires my son just put on his 17 x 9 Apex rims. Both tires were 245/40R17. He isn't rubbing either even lowered on RCE Yellows and with -.8 chamber in front.
