Default tire size for 17X8 rota torque

I just got my new set of 17X8 +45 offset rota torques and i haven't bought tires yet because im still trying to decide which size i want. I dont auto-x so i dont need a really wide tire but i would still like to know if i should go with like a 245 or so. I am lowered on progress springs so my back stock tires are about 1/4" from tucking and i figure if i go with wide tires on the torques i'll have to roll my fenders but will i need to roll both the front and the back because it seems like only the back would rub. I know that there are probably posts on something similar to this and i have run searches and all that but i would just like some first-hand answers on what people think i should run...The tire i am most interested in right now is the BFG G-Force T/A KDW 2 in a 235/45/17 but i dont know if it will rub or not.

Thanks

You probably want 235/40 tires...235/45 is taller than stock and will hurt your low end power. Also, your Rotas are +48 AFAIK. I'm getting 245/35 this week and expect to roll the fenders a bit. The tire is shorter so that should help rubbing issues but it is also nice and fat

245 will need some fender modification (rolling) 235 is probably the best bet. im running a 225/45 potenza re070 (sti tire and size) and it looks great on the 17X8 torque. iirc i read that the 070 runs a bit wider than the normal 225 tire, but thats probably not proven. any way, 225 is great, 235 probably a bit more "mean" looking, 245, keep it for the track.

edited, im dropped on prodrives, and IMHO i love the stance and the agressive look of my car. again, my opinion

It is proven. The re70 is as wide as most 235s.

I'm trying to pick out some 17" Rotas ... for spirited street driving (no auto-x) should I go with 7.5" or 8" width?

Subydude's article made me question my original idea of 7.5"

thanks

I plan on running P225/45R-17s on my 17 X 7.5 Rotas (48mm offset) with Prodrive springs. From everything I have read, this should be fine, as would a 17 X 8 wheel. FWIW, the range of recommended rim widths for the P245/45-17 is 7.0 to 8.5 inches.

7.5 or 8 would be fine. Since you aren't autocrossing or racing (you're sure you never want to? I ended up dumping my 225/45s and 7.5" wide wheels because I'm into autox now and I didn't orginally think I would be when I bought my tires) I'd base my wheel decision on available models, looks and cost, rather than pigeon holing yourself into a specific size.

Ok well ... are there ANY disadvantages to running an 8" over a 7.5" wide tire? Other than the price of the rim/tire.

Wider contact patch and less tire rollover.

Those sound like advantages though ... right? Sorry I'm such a noob to tires, I just want to make sure I spend my money wisely.

I'm wondering if there are any DISadvantages to going with the 8" width?

The wheels will be incrementally heavier, and having them be wider may possibly cause fitment issues. Those are the only reasons I can think of, and they're not good enough reasons to not do it, IMHO

Question

I feel like there's just too much to know!

From what I understand if you get the wrong offset, or any other number of wrong wheel characteristics you can blow your wheel bearings over time, etc.

At this point I've decided to buy a Rota wheel and most likely Hankook Z212's tires. The 17" rota wheels which I like that come in 8" width appear to be the Torque, Rev, and G-Force. I really like the Rev in Fully Royal Black. I believe this wheel has an offset of +48, which according to my searches on nasioc should be ok. and I'd probabaly go with a 235/40/17 tire on this rim.

I won't have to modify anything right?

Thanks all so much! Very helpful so far!

Unless you are totally 'slammed' you'll be fine with those tires.

Exactly!!! I had a set of Torques initially, but didn't like the color so I sold them. I got a set of 17x7.5" Tarmac 2's with 225 45 17 RT215's. Now I want to run 255 or wider for autox and track and need bigger wheels. I have just purchased a used set of Torques from my friend with 255 40 17 RT615's. Back to the wheels I had originally in a different color.

If I were you I would get 17x8 as this size will allow you more flexibility in tire sizing in the future.

The more I'm hearing this the more I'm agreeing, getting the 17X8 gives you future possibilities. However, will I have to modify anything on my car to accomodate this change? Will I be putting added stress on my wheel bearings or something?

No, you will be fine. The wider the tire you go with the higher the likelyhood of having to roll the fenders, but the rim itself in that size will have no ill effects other than increased weight.

but with a 235/40/17 tire I shouldn't have to roll the fender right? I bet at 245 I would though.

That's 2-3% shorter... I'd think you'd be fine.

You'd be fine. Even most 245's you'd probably be ok.

sry to sort of steal the thread, but while on the topic of tire and rim sizes would a 235/45/17 be okay to run with 17 x 8 Rota Torques? I still have the stock 04 WRX suspension. If it is okay now, would i run into problems later as i have plans to put springs on the car?

If you have a sedan I would go 17x8 all the way. Even if you don't plan to run a very wide tire, it still give you that option to. Also another plus of the 17x8 is that you can run a BBK and have it fit perfect where the 17x7.5 won't clear much more than the 4 pots. I would stick with a 235/40/17 on a sedan or if you want to push it go with a 245/40/17. The 235/45/17 as others have mentioned is just slightly taller and will hurt some power as mentioned. With a 235/40/17 on a sedan you won't have any rubbing, 245/40/17 you can even get away with almost if you have a light drop and stiff suspension.
