And if you are trying to make a quick pass..... It's a little scary.

I kicked on the DSC on the way to work today just getting on it a little through a corner.

I found my old T1R's hooked up reasonably well for autocross and resisted overheating pretty well, but I guess I'm comparing them to the motomaster all-seasons I had on the back...
I guess for the street, sticking like glue is a good tire strategy, but maybe you want to keep the grip down a notch for the steering with the throttle thrills? I like the older tires on my Dads miata as it let you do more throttle steering, but I guess on an M5 you don't need any more help with that...

My friend's E39 M5 can light up 275-section PS2s all day long. It does have some bolt-ons, though.

The thing was, I wasn't TRYING to light them up, LOL!!!

I like Dunlop Direzza Star Specs; it's a fantastic summer/track tire. Another good choice would be the Hankook Ventus RS-3. Both are available for less than $950 from Tire Rack.

So, the problem, as was suggested by another member in one of my other threads, was tire pressure. They were all at 40 PSI, the rear needed to be at 48, the fronts at 44. It only spins when I try to make it spin now. Which is a heck of a lot nicer to deal with!

How hash/firm is the ride with such high pressure front and especially rear ?

WOW! That high??

Usually, even with street tires, one lowers the pressure (to a point) to get rear drive grip.

I think that those same said hot rodders are more concerned with the ultimate strength of rear wheel drive IRS, when launching HARD on soft compound, wrinkle wall slicks (as compared to an S60, or 9" Ford solid) than anything else.

With so many aftermarket companies making brutally strong 300M (and stronger) half shafts/CV joints/etc. nowadays, there are some crazy quick IRS cars on the drag strips of America (and elsewhere) today!

Some manufacturers actually use unequal diameter l/r half shafts right from the factory to address straight launch, and strength issues.

Yup, made a huge difference.

When you are ready to replace them, the PS2's work even better. Haven't tried the PS3 yet, my tire budget has been reduced and now I buy tires that cost half as much (rated #2 by tire rack) and provide 1/4 the fun.

Sounds like most tires I've used. Low price, excellent reviews, not even in the same ballpark as the expensive ones.

The back tread is different from the front tread.

And they really suck.

Car full of FIVE PEOPLE.

I'm in 2nd, pull 3rd, hit 4,000RPM and the traction control light is flashing as she lights them up. This is MAYBE 1/2 throttle???????

Toyo Proxies T1R need lot of heat before it grip, so when the weather is cold, it is better to deflate a bit to warm up the tyre, and get enough traction when the tyres heated up.

Precisely. I've had good luck with Yokohama in the past, but also with Michelin. However this is a completely different car than what I've used them on.


Sorry, but the Hankook Ventus V12 is uniformly praised by BMW owners! Won some prestigious tests and super quiet with unreal grip.

You gonna take tire recommendations from an econobox owner? Good luck finding the best tire. It's your car.


I would say Hankook RS3 is more suitable rather than V12. I gave up my V12 after 15k driving and change to Michelin PS3. No regret at all. The problem V12 on my light car is no comfort when you put OEM pressure, the comfort getting better when it is overinflated, but the traction is poor. The straight line braking is very good, but aquaplanning during cornering is poor, that driving fast on bends during rainy days downright scary due the tyre can lost traction suddenly.

I can only tell you that the V12 is uniformly praised in BMW forums (and others) as a fantastic tire. That and its superb performance in the last Car and Driver Summer Tire Comparo which was very carefully structured testing and real quantifiable results, not just anecdotal testimony.

I agree. I have V12 on my S2000 now, I will find another brand when I need new tires. V12 lost traction on any wet surface even at moderate to slightly fast speed on a curve.

The Car and Driver test compares older generation of tyres, rhat is why V12 looks quite impressive.

 

[Colt45ws]

Hmm. Ill have to play a bit with my V12s next time it rains. I didnt notice anything odd last time.

 

[SteveSRT8]

probably a classic example of how different sizes within the same tire construction perform differently.

C&D used the PS2 as the yardstick, and one of the best rain tires was the V12. Per my info there is no substantial change in the V12 design, it's not a case of "old gen" vs. "new gen".

Due to all the anecdotal evidence I've seen i'm buying the newest Pilot Super Sports anyway. At 400 bucks a pop they really make you wonder if you're gullible or smart.

 

[kr_bitog]

PS2 even though it still considered good but is no longer the leader, from the C&D test only the Dunlop Direzza Z1 star spec is considered new (new generation)besides the V12. And that is exactly what revealed by the test result,that new generation has improved a lot. In the market nowadays there is already a lot of new rubber, like Bridgestone RE11, Goodyear F1 Asymmetric/2, Hankook RS 3, Michelin Pilot Sport 3, Pilot Super Sport, Continental SportContact 5P,Yokohama AD08 that it is somewhat better than PS2.

If the dry traction is somewhat more important than wet is the top priority, then PSS is great choice. However, on the wet this tyre may not the best.
