Closest to OEM Wheels width and offset

US market TRD lowering springs and front/rear sway bar kit. If you were asking about wheel spec, my post was the one with the picture attached.

I wouldn't run a 215 on an 8" wheel personally, but running a narrower tire will never give you clearance issues.

Figure out what your end goal is, and spend the money once. Might mean driving with the stock wheels/tires for a few months, but it's a lot better than having to do the same thing multiple times.

I agree completely, make sure your modification is helping you to meet a goal. For me I wanted lighter wheels, maintain stock feel, add a bit of rubber and clear my brake calipers without spacers. The brakes were to add thermal capacity for long canyon runs.

Just wondering if i didn't do any setup of camber can i put the tires directly with 17x8 ET 45 mm and 225/45/17 on the stock spec no wheel rubbing or side effect? because i head people said although 225 will give u slightly faster lap time in reality daily driving there are no big difference?

Tirerack.com recommends 235/40-17s with 17x8 on twins. They recommend 225/45-17 on 17x7.5. This makes sense since each half inch on the wheels adds approximately 12mm (keep in mind the wheel widths are not always exact). Running stock width tires on wheels that are around 15% wider doesn't make a lot of sense.

What are you going for when you change out the wheels? It may be better to get advice on how to accomplish your goal than whether or not a setup will be functional.

I would like to get the best on lap times and handling. so i guess 225/25/17 will be the best for me??

No offense intended, but is your driving really at a level where 10mm difference in tire is going to make the biggest difference in lap times?

If you're really concerned about lap times, get 225/45/17 Hankook RS3's and be done with it. They're not as good of an all around tire, but will be much faster than the Pilot Super Sports.

You'll also need a lot more negative camber than stock to use those tires effectively though.

Unless you're actually racing and every tenth really matters, don't worry about lap times in the slightest.

How much track time will it see? What kind of track use?

I would suggest nice light 17x7's with 215/45/17's on them.

Get the 17x8 wheels. Probably the most versatile size for this car if you're near stock power. You can run anything from 215-235 width tires with no issues.

My current track setup is 215/45/17 tires on 17x8 wheels. Looks slightly stretched, but functionally works well. Feels very similar to stock, just more feedback, turn-in, and grip -- mostly due to the tires, not sizing btw.

I'm mounting 235/40/17 tires next.

Really appreciate your advice. For me I will only go to track twice a month and the others time will be daily drive. Tenth seconds not really a big issue for me. Which I guess the pss 225/45/17 17x8 et45mm will do well with the job right? Cheers man

[wparsons]

Yep, that'll work.

I'd go with 215/45-17 tires on lightweight 17x8 wheels if its mostly a daily driver. The one thing that kind of annoyed me with it being my daily driver was the 17x8 +36mm offset track wheel set having WAY TOO MUCH grip with only 215/45-17 Kumho XS installed. Handling limits were so extreme that it just was not even as enjoyable to drive as it was stock, unless it was wet. Went with a 205/45-17 Max Performance category tire (actually just a little wider than the stock tread width too!) and 17x7.5 +40mm offset wheel setup and Boy Howdy...that is just perfect daily driver setup for me! More grip than stock (dry and especially wet - and especially in high speed cornering) but low speeds are just as fun and even more tossable. The better acceleration/deceleration from the .3" shorter diameter tire really improves the responsiveness and the small drop in CG height seems to add a little more stability.

Seriously, yall need to try a 205/45-17 Max Performance tires on lightweight 17x7.5 wheels....feel like shackles are taken off the car and it's agility is cranked up to 11 (thanks to reduced weight, smaller diameter, and lower CG!). Only thing that would make it even better is dropping 10lbs unsprung weight a corner with an AP racing Sprint brake kit...

No offense but are you sure that you got your numbers right? I am not a tire expert but I know that 205 is less than 215 and that means that your tire width is 8.1" instead of the 8.5" of width that the stock tires have. If you have experienced performance, it could be due to lighter tires, but I am pretty sure you have less rubber on the road than before.

Yes, the 205/45-17 Kumho Ecsta LE Sport has a tread width of 7.7" whereas the stock 215/45-17 Michelin Primacy HP has a tread width of 7.5". Tire section width is 8.1" and 8.4" respectively, but section width has little to do with anything other than wheel fitment and responsiveness - and the 205/45-17 Ecsta LE on a lighweight 7.5" width wheel is much more agile/responsive than the stock wheel/tire setup. Both tires weigh about the same, ~20lbs, but the smaller diameter, wider tread, and stickier compound of the 205/45-17 is what gives it a noticeable acceleration and performance advantage - at the expense of top speed (yeah...like I'm really concerned about top speed in my daily driver...LOL.)

Interesting. I was just looking at section width and neglecting the difference between section width and tread width. Thanks for the lesson.
