Completely new to buying tires and wheels.
 

Looking to add new wheels and tires as my first mod to the car. I've never bought wheels and tires, especially for a sports car. I'm thinking of doing 17x8's in the front (245/40R17) and 17x9's in the rear (255/40R17). Are there any pros / cons to having a different size in the front versus rear?

Wheels, 17x8/9 Rota DPT - Flat Black (5x100/114.3/e48F/e42R/73).
Tires, Bridgestone Potenza RE-11A.

Thanks for all your help in advance. :thumbup:

Don't ruin your nice new sports car with cheap wheels.

Sure wheels are round, blah fucking blah.

Put it this way, would you go out and spend $800 on a suit and wear $20 shoes?
$20 shoes and $100 shoes do the same thing though right?

But its always about balance. If you can afford a new car, you can afford genuine parts.

Yes, yes I would.

Pros to staggered fitment:
- Looks good

Cons to staggered fitment:
- Increases understeer
- Increases weight
- Limits options to rotate tires

If you go that route, you'll want to match tire circumferences as closely as possible front-to-rear, i.e., 225/45/17 F and 255/40/17 R.

That combination should fit fine on 17x8 F and 17x9 R wheels, but you may want to confirm there won't be rubbing issues with a 255 in the rear.

Along with those main components, also keep in mind having/getting the proper lugs and hub-centric rings for whatever wheels you get.

My advice, don't go staggered. Just stick with 17x8 245 all the way around. It'll handle much better and it'll be cheaper.

Completely spaced that it's a percentage of width for profile. Thanks, that could have ended badly.

go with a 17x8 square setup

And you'd still take 8's over 9's? Looking for greater traction, but keeping in mind not to add too much weight. I'm moving away from the staggered setup now. At this point just looking for a good size that's larger then the stock 7". Car just doesn't look right from the right with those skinny wheels and tires.

Seems like a lot of folks are putting Rota wheels on their cars. Is there any reason you don't like them other then their price?

Also think about use (street/ax/track), ride height, camber, (no) toe, spacers (not too big to save bearings). For me 225/45-17 all around on 17x8 works well on the street. Have 235/40-17 (less common size) tire with same rim size for track. Also have Jackson Racing SC, Ohlins, camber, about 20mm drop, 12mm spacers for stockers with winter tires to clear BBK. To each their own though, stagger looks cool but it changes things...much of the change can be addressed in other (usually expensive) ways to still work pretty well but spend time talking to experts like @CSG Mike or @CSG David and others like them before taking the step. Bigger rubber tends to numb steering response, slow you down and affect gas mileage, among other good points already mentioned. RE11A is a great tire choice IMHO for varied use in warm months/climates...do not drive or store in low temps per instructions.

Depends on how prideful you are. Rota copies other manufacturers' designs, thus they have very little design/development costs and pass the savings on to you. There's a lot of debate on the structural integrity of Rota wheels, but it's mostly hearsay (though each side would like to convince you otherwise).

I've worn a suit with sneakers

but they were $50 sneakers, so... compromise?

:bellyroll: :iono:

Buy whatever wheels you like. Don't let someone else tell you what to spend your money on.
I went with a staggered setup because I knew that cosmetically I wanted my wheels to look flush with no poke. If I went with a square setup on the wheels I wanted then I was either going to have too much tuck in the rear or too much poke in the front. I was able to keep my tires the same size on all 4 wheels and you can barely tell. If this car is a daily driver then understeer and weight really aren't going to make a difference.
Just look at a ton of pictures from different angles...even on other cars if you can't find a lot of pictures of the wheels you want on a Twin. It doesn't matter if you spend $500 or $4,000 on your setup...just as long as you love the look of it.
