Default Rubbing witth 17x8,5?

Hy!

I have 07 wrx sedan. I'm thinking to get advan rs 17x8,5 et48 wheels.
What tyres will be better - 235/45/17 or 235/40/17 and less rubbing?
Also I'm planning to lower my car with prodrive springs.
Looking for some advice guys!

Tomas

You'd definitely be fine with 235/40-17, and most likely fine with 235/45-17. I think the 235/40-17 is closer to stock diameter.

so what tyre size your recommend? 235/40/17? Would be nice not to have any rubbing issues, because i don't want to roll my fenders... i presume prodrive springs will not lower my car so much that any rubbing could appear.

with a +48 i think you'd be ok running a 245/40 without rubbing, and that would be a really good tire size too. if you want to be really safe you could run the 235/45 or 235/40. i personally think the 245/40 would look the best and give you slightly better gearing as the 06-07 wrx's are geared really tall. i never tried a 245 tire on my setup but i'm pretty sure that i could've run that size tire without rubbing. maybe someone else can chime in. a +48 should give you enough fender clearance.

Well, i have 4.11 FD not like you guys have 3.7 FD, because mine wrx is edm spec. That's why i don't want shorter gearing. To be really safe at first i want to try 235 wide tyres, and then if there will be enough clearance maybe i will go for 245. So as i understood you guys recommend 235/40/17 over 235/45/17?

well with a 4.11 FD i'd get teh 235/45. a buddy of mine runs that size on his 17x8 rpf-1's and is really happy with them, i think they look really good on a 8 inch wheel too. i really do think you'll be ok with a 245/40 though. also go to tire rack and look at all the specs, some tires run a bit bigger than others and some 235 might be as big as a 245.

i did some research and find out that 245/40 tyre size would be the best for 8,5 wide rim and closer to stock tyre size. I'm planning to take bridgestone potenza re050a tyres, are they big? I'm worried about rubbing issues with 245/40 though...

with those wheels, tire size, and springs, all you'll need to fix any rubbing is a mild rear fender roll.

I know many people who run 245/40-17 and also 235/45-17 .... the 235 is slightly taller than stock and does have a little effect on the overall gearing. 245/40-17 is the more popular choice but, most people end up doing a little fender work

I'm running Falken 452's 245/40/17 on 17x8 Rota gForce. I forgot the offset though. I love this set up and I'm going to keep using the 245 width when I replace this set of tires. I wouldn't go with a 45 sidewall. It makes the sidewall look just to tall. A 40 sidewall looks better imho and doesn't throw your speedo off by more than 1 mph. My car is lowered and after the aglinment I had no rubbing issues.

you have 06 wrx sedan? i'm planning to get 17x8,5, so it's wider then 17x8... That's why i could get rubbing in the rear with 245/40/17...

a wider wheel isn't going to cause rubbing, low offsets and/or taller than stock tires do. fwiw, i have 18x8.5 +48 with 255/35/18s and i have no rubbing whatsoever.

with 245/40/17 on a 17x8.5 +48 wheel, the only thing you might need to do is roll your rear fenders. you could even go with 255/40/17 if you wanted to, but you would definitely need to roll the rear fenders for that.

As far as I know the 06 WRX won't accomadate 255 in the wheel wells with out modding. STi can use 255 without mods. As far as widths go 235 is plenty for the street but I prefer 245. If I could run 255 I would but for my driving situation it's not worth the effort or money. 245's do look good and they really fill out the wheel wells.

my 04 sti with rce yellows wouldn't fit 255s without rolling the fender . it didn't cost me much to have them rolled.
