Just purchased some 19" wheels.
Front 19 8.5
Offset: 45mm
Backspacing: 6.25
Back 19 9.5
Offset: 45mm
Backspacing: 5.86"
What size tires would work best?
I'm getting the Brigestone Potenza RE-11's.
Thank's

You can run 245/35/19 front no problem. You still have room for 5 or 8mm spacers to make them flush w/o rubbing... that would bring your front offset to +38 or 40mm.

The rear is more tricky at +45mm.. I'd recommend you 265/30/19 if no drop, 255/30/19 if dropped.

What kind of wheels did you buy? BBS CH-R?

This is ridiculous I wish we could put more meat back there we need it with all this power. My bro inlaw has a g35 and they can fit up to 305's without modification to bodywork and its a 3.5 v6. So it would be possible to fit 255 tires on the front on a 8.5 rim with same offset?

Roswell

I hear u.. I can't even fit 275/30 w/o rubbing. But I've seen ppl using 285/30 with the right offset.

As for the front, u can use 255/35 on 19x8.5 +45mm no problem. But I'm not sure if it will help the handling.

The wheels I got I want to use for the track there inexpensive.... BE by Breyton GTS-AV(Black Painted) 19" from tire rack there having a closeout. insane price. Im ordering a set of Forgestar's for street. those will have proper offsets.
Dont know why tire rack only recommends the 45mm offsets front and rear?
The car is dropped with H&R sports.
AS far as front I really like the 235's... car turns great at track and 265 rear balances the car super.... Dunno if 245 fronts would help any...
Guess Im just gonna make it to the shop to have my mechanic put on one of the rims in the rear without a tire just to see what we up against.I'm looking into maybe having my rear fenders rolled so I can run 275"s on the Forgestar's.
Thanks for your advise.

Roswell

No prob, if ur ready to roll ur fenders.. The sky is the limit.

But with stock fenders.. 19x9.5 +45 with 265/30 will be very close on ur H&R drop.

I have a friend with the Breyton in black.. I can post pic in this thread to show u.. They look hot even at stock height!

Just as Meng says, it will be close but it might work if You run a narrower tire brand e.g. Toyo or Dunlop. Michelin won't work because they run much wider.

On H&R springs, I had 9x19 ET54 with a 10mm spacer so the offset was 44. I ran 275/30/19 tires without rubbing issues (I think they were Pirelli Pzeros).

Roswell

Matt, r u saying u ran 19x9 +44mm with 275/30/19 w/o rubbing? Noooooo .. I don't believe u! Lol

Edit: I'm also on 19x9 +44mm with my oem , and my 255/30/19 are closed to rubbing, no way I can squeeze 275/30 with this set-up.

Here is a pic of the rear - -9x19 ET44 275/30/19 Pzero
On H&R Springs.

EDIT: I thought about it and maybe the estate has a different shape of the fenders/ fender wells?

Roswell

U r Matt the greatest. I dont think i can fit 275 on mine. What u think?

Roswell

OP , here is the Breyton i was talking about...

To be honest I don't think it's worth the hassle of getting new tires.
Yokohamas are more "square" than Dunlop, Toyo, or Pirelli so they run a bit wider.
If You really wanted 275/30/19 You'd need to get one of those tire-brands.
It will look almost the same.
I honestly think that Your setup looks better because the face of the rim is not "sunk" into the tire.

OP: Do you like your Infinity Basslink?

Roswell

Thanks Matt for the clarification.

285/30/19 with a +35 offset rear here Gonna fit a 295 when these rears wear out

I'd recommend a 235 / 245 up front and a 265 rear
