Need some advice on tires
 

So I've got some 17x8 +37 advan rg2s coming in and I was wondering what tires I should buy. I've read up on the Michelin super sports but that's about it..

I don't commute all that much and want tires that would be good for my ventures on the track and in canyons..

any advice is much appreciated :thanks:

Are the wheels gonna be used for daily use or only thrown on for track days/spirited driving?

A good amount of daily use as well. But no really serious day-to-day commuting.

BFGoodrich G-Force T/A KDW 2. The Super Sports are marginally better for the spirited driver, but these are a bit cheaper and they tend to last longer.

Or, if you're really hardcore, Kumho Ecsta V710's.

Also, what tire size would be appropriate for my 17x8's? 225/45?

Yup, or go to a 235 if you want slightly more grip/comfort but a tiny bit more flex.

Would the increase from 225 to 235 affect speed at all?

Michelin PSS are great tires for the street/track

It'd change the gearing slightly if you left it as a 45 profile. If you want your speedo to be more accurate, then going down to a 40 profile would help, but i'd prefer the additional grip of the 45 than having a 100% accurate speedo. We're only talking a couple of mph out.

225/45/17 is the exact same difference in diameter from stock as a 235/40/17, just in the opposite direction. the 225/45's are 0.3" taller than stock, and the 235/40's are 0.3" shorter than stock. Neither is significant in speed readout (my 225/45's GPS as the same speed as indicated by the cluster). 235/45/17's are 0.7" taller than stock, which will be more noticeable, but nothing that would be something to worry about.

If you want grippy tires and don't care about a bit of noise and faster wear look at the BFG Rivals, Dunlop Z2's, Hankook RS3's and Kumho Ecsta XS. I daily drive on 225/45 Z2's and love it. They're noisier than stock, but not annoying except on really old/rough pavement.

My car is mostly street with a bit of auto-x/track and I went for the PSS, loving them so far they've really transformed the car.

A larger and/or wider tire will marginally affect acceleration (ie. you'll accelerate slower with a larger and/or wider tire).

A few more tire recommendations: Toyo Proxes R888 and Pirelli P Zero System.

Running PSS on 18" 8.5/9.5. They perform really well. I have 225 in the front and hasn't lost any sharpness. The tires provide pretty good road feedback also. They weren't quite as heavy as I expected them to be. Would definitely recommend them. The only disadvantage is they seem to be noisier than other tires. A bit of extra road noise, but the little rocks and gravel in my city just get sucked up into them.

Pilot Super Sports are great.
Lower-cost alternative: Hankook RS-3

My first choice on size would be 235/40-17, but very limited selection, best bet Dunlop Direzza ZII, but $194/each at Tire Rack.
2nd size choice would be 225/45-17, huge selection (including the PSS and RS-3).
