If you liked the Fuzions you might consider Potenza G009's. I just used up a stock sized set in about 42,000 miles. I've got about 4/32" left and have a new set of 225/60-15's mounted and ready to go on light rims(?)15.5 lbs. I drive 85-90 miles/day, 50/50 back roads / highway. Just waiting for my next oil change to throw them on. My stock rims will be for snows.

 

What is the tire size that comes standard on the I30t?

 

215/55-16 on 16x6.5 rims

 

bigger than 18's you end up losing power, 15-16" higher acceleration 17-18" higher top speed (supposedly) also the smaller the tires the more bumps your gonna feel. just me .02

 

Last week, I changed my 215/60 x 15 Fuzions and stock 15" I30 alloys for a set of stock 16" I30t alloys with 215/55 x 16 Goodyear Eagle RS-A's. I noticed some major differences right off the bat:

1. As an analogy, it sort of feels like I traded sneakers for boots. The car is not as quick off-the-line as before and it feels like the engine is working harder to bring it up to speed. The added weight of the larger rims and tires
(unsprimg weight) are probably the reason.

2. On the upside, the ride is much more stable and secure, especially on wet roads.

3. On turns, it does require more effort to achieve the same turning radius, as the car wants to take them wider than before. My previous set of 15's were easier to maniuplatr and used to knuckle under on sharp turns, but not these -- but the advantage is a flatter turn with less body lean.

4. Braking is definitely improved. The 16" tires maintain their footing and resist locking up...something, I used to do on the 15" tires.

5. With the the 15's, too much pedal spun them on takeoff, whereas I have yet to spin the 16's on launch.

Dimensionally, both sets of tires have similar diameters (with about a 0.71% difference). The major difference is in the section width with the 16's having a wider tread thanks to the lower aspect ratio.

So, all in all, the upgrade has more plusses than minuses. In a stop light grand prix, though, the 15's hold the edge.

 

id stay with stock.
after upgrading new tires, is it me or when u floor it, u peel out like crazy?

3.0 FTW!

 

I think this is the setup you are looking for...



J/K.....lol

 

Technically, they are both stock I30 wheels, but you could argue that the 15's were stock for this model. Anyway, I'm going to hold onto them just in case I feel like switching back.

BTW, The stock tires that came with the car were Michelins: biggest waste of rubber on the road, IMHO.

As for peeling out w/ new tires...yeah, it happens every time until you break them in and wear off the crap that is on them, like labels, markings, coatings, "beads and whiskers," and so forth.
