Going down the highway last night I ended up with both passanger tires going flat. I have no idea what I hit but now its time for new tires. I dont know how I couldnt have felt it, the hole in the back tire was big enough to stick my finger in. Four hours later I finally get my car home. The good news is theres no damage to the magnesium rims.

So now I need 4 new tires. I have the stock mags, 17x8.5 18x9.5. Anybody recommend any tires and sizes.

 

If you want to stick with runflats, try the Firestone Firehawks. I have a set and they are very good.

If non-runflats are wanted, the Goodyear GS-D3s are a good buy. Some have bought the Firestone Wide Ovals - may be a decent alternative.

 

If you want an extended mobility tire, many have and like the Michelin Pilot Sport ZP. If you want a non runflat, the Goodyear GS-D3, the Michelin Pilot Sport PS2, the Continental Conti-Sport2 and the Nitto 555 are all popular choices.

 

I just got a set of TOYO's and boy what a difference. Non runflats are the way to go. Much more grip and quite a bit quieter. I LOVE them! AAA is my piece of mind.

 

Yea I had non-runflats before this incident. AAA is who got me home. I was thinking of the Toya Proxes T1R or the Nitto 555s. Are the Toyas worth the extra money? Also, what size tire would you recommend on my stock rims?

 

I read here multiple stories of the Nittos having no traction in rain, with dire consequences. If you drive in rain, you are pushing your luck!

 

did the police try to stop you with a stop stick??????
or did some back over a one way tire killer at a parking garage?

anyways, i have the firestone firehawks. they are better than the goodyear stk tires. but are still very hard in comparison to the non runflats out there. i dont yet know if i will be going with them again here soon when i replace mine. i like the run flat idea....but the xtra $$$ and the loss of certain performance is acting like a tug of war game on what to buy next time.

haha, Im a good boy. Cruise control AT the speed limit everywhere I go.
Rain is not a concern. I really only take it out on nice days. My crappy Saturn is always on call when it rains.

I think Im going to go with the Nittos from discounttiredirect.com. Is it best to go with the sizes they recommend? 245/45 and 275/40.

 

 

...then check a recent edition of Car & Driver. Although they "only" used a 325 BMW as a test mule, you are very likely to experience similar results with your C5. To minimize variables such as driving techniques, track surface temps, etc, C&D enlisted the help of the Tire Rack and their test mule vehicle. Although the track used was small, it's lined with sprinklers that can soak the asphalt. "It took three days to perform all the tests. We accerated to 50 mph and then braked to a standstill. There was a benefit to that lower speed: It ensured that we were measuring the braking performance of the tires and not just brake fade."

"In addition to factoring the wet and dry scores, we gave points based on a tires's price and tread-wear grade, which is a rough estimate of how long a tire will have usable tread." "Our test focused on measuring performance, so we decided that results in the dry-lateral grip, for example - would carry the most weight."

So, without further adeau, here're the results:

(Best to worst):

NUMBER 1: Goodyear GSD3: "As an all-around performance tire, you can't beat this Goodyear. It was the best performer in all three wet-track tests and was very competent in the dry. It generated .94g on the dry skidpad, only .01g off the first place (dry) BFGoodrich and tied with the Yokohama and Hankook.
The Goodyear gripped so well, that you might not have been certain that the road was wet. It held onto the wet track with .82g of stick, an impressive figure considering the worst tire in that test made only .67g.
...And like the Continental, the Goodyear had a high 280 trad-wear grade. At $145, ieach, it's $34 cheaper than the most expensive (guess which tires have THAT distinction!).

2nd place: Continental ContiSportContact 2: "It simply didn't feel as sporty as the others.....on dry surfaces, the Conti never rose above third from last among 11 tires. It felt soft and imprecise. But in the wet, the spread from best to worse was 15 percent, which made for a larger point spread (giving the Contis a boost). Plus the Continental had a 280tread-wear grade that was the highest (tied) for this test.

3rd place: Yokohama Advan Neova AD07: Excellent dry performance, but a bit on the slippery end in the wet stuff - expensive at $175 apiece.

4th place: Michelin Pilot Sport PS2: "At $179, the PS2 is the most expensive tire in the test." Competent, but expensive sums up this tire.

5th place: Hankook Ventus R-S2 Z212: At $99 each, these are the least expensive tires - very good on dry pavement, but "greasy and slow to recover" on the wet stuff.

6th place: Dunlop SP Sport Max: "In the dry, the tire seemed to lose its confidence..."

7th place: Pirelli P Zero Rosso Asimmetrico:"In the dry-lateral-grip test, the Pirelli tied for second to last, and it finished seventh in the dry-braking test.

8th place: Toyo Proxes T1R: "...the Proxes never placed higher than eighth in any test"...nuff said!

9th place: Bridgestone Potenza RE050A: "it felt dull and disconnected and was somewhat soft and imprecise when driven hard."

10th place: BFGoodrich g-Force T/A KD: Outstanding performance on dry surfaces, but very scary on wet surfaces - don't get caught in a rainstorm wearing these shoes...

11th place: Kumho Ecsta MX: "They didn't offer much grip and the time of 30.28 seconds in the dry autocross was .62 second slower than the fastest tire. That may not seem like much, but our course was only 0.3 mille long, and on a longer track, that gap would be commensurately greater." "And although the MX - at $136 per - was the third-least-expensive tire in our test, the high score in the price category wasn't enough to regain ground lost in the performance tests."

On a congratulatory note, the first place tire is made right here in the USA by an American tire company
