Just bought a set of Z06 wheels (factory Speedlines) for my base C5 coupe. Looking forward to getting them on the car, but man I never thought that getting tires would be so hard!

I have Michelin PS2's now and love them, but not real excited about buying another set (expensive) so I have been reading through a lot of forum threads and came across Vredestein Sessanta as possibly an excellent alternative. I should note here that I don't track or race the car, just spirited street driving. Since the car is not a DD, wet performance isn't critical, but also don't want to get tires that would put me in the ditch if I get caught out in the rain...

When I look at the sizes available for Vredestein Sessanta tires, it appears that I have to go with P275/40ZR17 up front and P295/35ZR18 out back.

My concern here is that the difference in diameter is only 0.4" (26.1 - 25.7). Is this going to give me TC problems? Most posts I see state minimum of 0.5".

Second question is what about speedo calibration? Remember my car is a base C5, so it came with tires that were 25.7" and 26.7" in diameter.

I would love to go with tires that are P275/40ZR17 and P315/35ZR18. This would retain the original tire diameters both front and back and would give me a nice wide tire in back (going for looks). However, I can't seem to find any street tires in the 315 size.

Appreciate anyone's thoughts on the TC and speedo and the tire sizes I am looking for.

Thanks!

I just put a set of Vredestein Sessanta on my 01 Z06. I used the 275's up front and 295's on the rear. No problems at all. The ride is quieter then the F1's I took off (they were original to the car). I paid $944.00 shipped on the tires. They have a crazy looking tread pattern. Bridgestone has a deal going right now on stock sizes for the Z06
($744.00).

I have the Bridgestone tires on mine and love them!

The Vredesteins and the Bridgestones both seem to get a lot of positive press here on CF,

From what I can tell, the Vredesteins might hold on edge in terms of performance, but they are also about $200 more than the Bridgestones.

I am beginning to hear about/read about the BFG Rival as well, but it is pretty new and not a lot of real world street experience with these yet, at least not on C5's. They are a bit pricier too - looks like around $1200 for a set from Tire Rack.

rival is a completely different tire. it's an extremely aggressive street tire that has maximum dry performance and likely a 15k treadlife. the NT05 is other popular choice in this category

the re760 is a street tire that has a 30k mile life if you don't drive hard and does well in the rain but won't hold a candle to the rival or NT05 in the dry when warm

the rival is a dual purpose tire made to drive to the track, run laps and come home

the 760 is a street tire that can't take the heat of actual track duty but performs well when cold, sheds rain and lasts 2x as long or more

on the street the 760 is already capable of pulling corners WAY above the speed limit.

I have the Vredestein Sessanta tires, with the P275/40ZR17 up front and P295/35ZR18 out back. and like them quite well.

Re the speedo, no worries as the wheel sensors take care of and changes, including a different diff ratio

racebum

thought the 275 was recently discontinued ?

Some have reported that the rears run quite narrow, what have you found??

On the Vredestein's the rears are 10 inches wide. The Good Year F1's are 11 inches wide. I think it's because the Good Year has more of a squared shoulder and the Vrdestein's have a rounded shoulder. I do like the look of the Good Year's better especially in the rear.

I have them on one of my cars and don't care for them. They tend to flat spot when the car sits for awhile until the tires warm up.

I tracked my Vreds' at a hpde @ road atlanta, pretty good grippy sticky tire

The wheel sensors only count revolutions, they have no idea of the tire circumfrence, and cannot correct for a different rear ratio either. It takes a program change to correct speedo for tires or diff changes.

Ok...Finally got the opportunity to show everyone what I've been talking about. Here's what Nitto Invo's and Vredstein's look like together. You can see they are the same "width" from the stacked height but the tread section is way more round than that of the Nitto.

In a comparison test in a German car mag which included most high-end tire brands including the PS2, the Vreds were rated number 1. Their wet weather performance is way ahead of all others tested. I have them and I've had the Michelins, too. I like them a whole lot better, they are excellent in wet weather, stick like it's dry. Pricing is good, too.

What do they do when you put the weight of the car on them? Do they flatten out some?? BTW - Thanks, the photos have been really helpful.

Got em at Tirerack, stock Z06 sizes too.......
