Tires! Which is best?
One thing I have read over and over here at the CorvetteForum, is how bad the Dunlop tire in 255/60/15 is. Apparently they are absolutely horrid in any kind of moist or wet weather. You can always say "I never drive in rain" but you never know when you will get stormed on during a cruise.
The Best of Corvette for Corvette Enthusiasts
There is an old version and a new version.
Old
Dunlop Radial GT Qualifiers text on sidewall, mfg by Dunlop before they were bought by Goodyear.
New
Dunlop GT Qualifiers text on sidewall, mfg by Goodyear/Dunlop with redesigned tread compounds and sidewall contruction.
I have these and have driven in HARSH rains while going to corvette show 50 miles away at our Treasure Island casino at the end of July. I had to use my wipers in fast mode and that wasnt really fast enough to keep the vision clear. Needless to say, the Dunlops performed excellent in this major wet condition.
Also 255/60/R15s, so stay clear of the old ones as they are probably dry rotting by now anyway.
The tread of the Dunlops look much nicer also than BFG TAs or Indy500s or GTIIs, which all look more like 1976 Ford LTD sedan tires IMHO.

He was full of praise for them & I'll certainly consider fitting a set on mine when I wear out my (new!) BFG's. The way I figure it is that if I'm spending lots of cash on handling improvements (springs, shocks, sway bars, etc) then I'd be stupid if I scrimped on the most important things ie the bits that keep you stuck to the road. My 255/60-15 BFG's are pretty good but their limitations were exposed when I was following an Elise around some fast twisty bits. The Vette cornered flat, steered well, coped with the rough surface well, but those darn tires were on the limit of their grip and were loudly complaining. Sure, I took the Elise on the straights but the point of a sports car is to be good on the bends, so it's more grippy tires for me in the future


I will be pulling off my original 24 year old Polysteel Radials and getting a set of Firestone Indy 500's soon. At $61 they look realy good and they get lots of great ratings from customers at the Tire Rack. What else would I want. (except maybe reasonably priced set of NOS Polysteel Radials, yea-right
)Edit: I would like to add that when I asked the most experienced tire guys in town the question: "Who makes the best tires? The answer was "Michelin". They said they do not have defect problems with them, they seldom need to add much lead to them to get them to balance and they last a long time. They also said they were not worth the extra $$$ in their opinion so take that for what it is worth.
Now if they would just make them with the solid white letters in my size, maybe I would think about it.

He says to trust Michelin, Bridgestone, and BF Goodrich.
He says to avoid Pirrelli and Continental like the Plague...
You don't want to know what he says about some of the discount import brands.
That said, I've heard great things about the Michelin Pilot Sports. I'll be running Potenzas since they make them in the size I need (255/50-17)

Michelin have always been up to the job, the best "S" rated tire I ever had was a Michelin.
Bridgestone have a good name these days, but I can remember when the only people using them weren't afraid of death!
Don't trust Pirelli? Does he say why not? My only personal experiences with Pirelli were in the early 80's (didn't use them often as they were so darn expensive). Around that time they were one of the best tires that you could fit to a m/cycle (Pirelli Phantoms). Stuck to the road like glue, even from cold, whether the roads were wet or dry. But they wore out real quick. I once had them on a car I bought & after I replaced them with a quality alternative (cheaper, but not import cheap!) that car became a liability on bends in the wet. I would have thought a manufacturer who could produce tyres that were superior to most of the competition for bikes would have also made good ones for cars? My sisters friend recently owned a place in London that specialised in tuning the hell out of Porsches. He got a lot of his specialist parts from the US & developed his own engine management chips. He must have been good as the rich & famous were his customers & he would do a "basic" upgrade that gave 600hp at the wheels (Dyno proven). More expensive upgrades unleashed a lot more
Not bad for a tuned VW Beetle
(you wouldn't believe how embarassing it was when he asked what the net power o/p of my L81 was
). One of the brands of tires he specified was Pirelli. With that much power produced I wouldn't have thought he'd spec cruddy tyres (esp knowing how 911's handle in the wet!).My Dad bought one of the 1st Saab 900 Turbos in this country & later had a factory approved water injection system added, with close factory involvement. The factory specified Pirelli tires.
The L81 owner on this forum is very interested in handling improvements & has done the sort of things to his Vette that are regularly recommended here. He admitted to being very dubious about the Pirellis at first (didn't look right on the Vette compared to the BFG's, ugly tread, 2 extra plys) but doing some test drives around his "test track bend" let him take the bend significantly faster than he had done before. He's never mentioned any problems with them since (like "Holy cow, I took them out in the rain & slid off the road"!), so I guess he's still happy with them.
I don't own shares in Pirelli or have any loyalty to them, but I've never heard anything bad said about Pirellis apart from the cost of them & the life expectancy being shorter than that of a Hamster in a blender! I haven't had any conversations about tires for quite a long time, so maybe I've missed something?! Has Pirelli tire technology got stuck in the 80's/90's, or was your mate refering to them from a Drag racing perspective? I'm genuinely confused here as Pirelli tires used to be fitted by people who were interested in getting around corners as fast as possible. Have they gone "downhill" over the last few years??
He wouldn't be alone.
and had four new Pirellis on a t-Porsche, sent him to a Hunter GSP
9700 and three had tread separation. It was not the product. He now has
Bridgestones and NO problems.
Mind you the tires, Pirellis, were almost $2000. We hear this over and over.
Continentals aren't much better. Strange thing is that they make great motor
cycle tires. Go figure.
that many know nothing and many are very informed about tires.
Some results:
Most troublesome tires - Pirelli ,mainly tread separation, other problems too.
Continental was second for many reasons.
Most underated tires - Bridgestone
Most over rated - Goodyear
Most owned by performance drivers - Michelin/BFG & Bridgestone
Most important decision influencing replacement tires: get this, OEM brand?!
Some other things we found out:
One in twenty knew what the UTQG ratings meant!! (Porsche/Corvette/Ferrari owners too)
One in ten have upsized tires and or wheels INCORRECTLY! When you inform
them of this 'problem' they go nuts!! Go figure.
AND THE BIG ONE::
Virtually none do anything to insure proper tire wear and safety: not even checking
inflation more than once or twice a year!! Can you say alignment or balancing? NO.
Our conclusion: it's a sad commentary from and about "car buffs".
problems as reported by our customers.
I would stay away from them at any price.
The Michelin Pilot Sport is not the tire to get if you intend to autocross. The Falken Azenis or Kumho MX will be far more competitive at a cheaper price. The BFG KD will outperform the Pilot Sport at a similar price.
There is really no way to know what tire will be best by looking at them. Last week I drove a few tires on a wet handling course. Two tires were out of the same mold, they had the exact same size and tread and the same internal construction. The only difference was the rubber compound of the tread. The difference in lap time was almost 6 seconds on a 42 second course!
My point is that since you really don't know what compounds and constructions are used in the aftermarket, the only way to try to select the best tire is taking the opinions of others who have tried them on cars very similar to yours. In the end you just have to take an educated guess.
Need to know what size I should run before looking at brands. HELP.
BTW, stock rebuilt rear suspension.
