Default Vitour P1

Anybody try these? I’ve run:

- Nitto NT01 very consistent tire and I like them very much. Very predictable.

- R888R classic hero-lap tire and not very consistent especially when pressures range more than 3 or 4 pounds during a session. Definitely had a sweet spot, it just wasn’t very large.

- Nankang AR-1 I like this tire as well. Good wear good pressure and high heat tolerance. Every bit the equal of the NT-01.

I need an intermediate versus a slick as I drive to and from the track. Just ordered the Apex 19 inch set up. Vitours seem to be getting some good press. Unfortunately, not from people that I trust yet.

If you run SCCA they are banned. Some word of mouth type of reviews say they're pretty good.

I’d like to understand why they are banned. Banned because they aren’t safe = I’m out. Banned because of sone competitive advantage vs. other 200TW intermediates….well then you have my attention.

Reviews I’ve seen claim to pick up 1 to 4 seconds vs. the other brands and all say stiffer sidewall. This is a known issue with the C8Z is a switch to 19”s cost you sidewall stiffness and upsets the handling. Don’t mind being a beta-tester.

295/25/19 and 345/25/19 are in stock.$1,950 a set….not cheap, but absolutely less than R7’s,

Most SCCA members would also like to know why they were banned because they appear to meet all of the written requirements. The "unwritten" rule appears that since Tire Rack doesn't sell them (and they are a high level sponsor) that perhaps they have been holding off on allowing these.

And, and update as to the tire being "banned" in SCCA. If you run autocross and are in the CAM class you can run them. It also appears several other organizations are going to allow them next year as a result.

There's plenty of C8Z / E-rays running the Vitours with plenty of reviews and feedback on them. They seem to out last the Yoko's and don't require a lot of heat to grip from the start. Lap times on a track seem to stay consistent across a 20 min. session as well, no hot laps 2-4 and then cooling required like a few which like to get "greasy".

Saw an E-Ray and C8Z07 run those sizes at the Ultimate Track Car Challenge at NCM last month, though no one at SCCA TT Nationals were on them as they weren’t legal though they just made them legal for Cam and XS classes I saw posted today. Top 200tw are as fast as the old 100tw from what I’ve seen, so I don’t believe they’ll be a step down from what you’ve ran.

That’s only for National events. They are legal for regional SCCA events as long as your region didn’t ban them. Our region didn’t ban them, so they are legal. Originally there was concern about availability and sizes. They are now legal for CAM and XS class for National events.

There are new sizes coming in January ‘25 that will be stock diameter, at least for my ‘24 Z06.

What sizes? 265/325 in 20/21?
The 295/345 are a good width for 19s but nervous of them being 2” shorter OD.

Shorter OD shouldn't matter much, especially if the front/rear ratio is similar to stock. This would shorten the gears, but with DCT, not sure if it'd matter much, either.

It'd be a much bigger problem if OD was higher than stock. I had rubbing on the wheel liners even with stock tires, so anything bigger would be a 'problem'.

The 275/35-19 fronts with 325/30-20 rears are almost exactly stock diameters, and will maintain the front/rear ratio so the computer is happy.

Black Friday sale on these tires.
The Vitour Tempesta P1 is available at VitourP1.com Use coupon code: P1BF10

That's just a link and sharing the code, I get NOTHING from anyone clicking on this. Type the URL in your own if you're skeptical for any reason. Just sharing.

I just looked at their sizes, and realized they have amazing combinations!

One of the issues I've had with Z06 / Z07 was soft side-walled smaller diameter tires numbing down the road feedback with OEM suspension. I just switched to coilovers myself, but if someone would like to stick with OEM shocks, a 19" set of 295/25/19, and 345/25/19, or an 18" set of 295/30/18, 345/30/18 could do wonders.

Here's their full specs list:

I don't think this tire is good for me (only good for a few laps before it overheats), but would love to see these sizes on other brands : )

One of the huge benefits of the Vitour is that it *doesn't* overheat and get greasy. Lap times have shown this over and over. The North American representative (Dallas Reed) runs both a C8 Z06 and Eray on these tirees and has reported time and time again how they perform better than the Yoks' when it comes to heat. Wondering where you got your impression otherwise.

I was referring to the GRM review of the tire: https://grassrootsmotorsports.com/ar...-buyers-guide/
One of the quickest 200tw tires we've ever tested, the Tempesta P1 is quick to turn on–one hard lap, in our case–and drives like a a typical R-comp, offering abundant grip, an eagerness to dive into corners and progressive breakaway and recovery. Heat soak sets in farily quickly though, causing grip loss that only increases as the tire is pushed.

There are discussions from the Vitour camp that the tire has changed since the early tires that Andy got for testing with GRM. He has another test coming up soon and I'm sure the article will show up on GRM very quickly afterwards. Will be interesting to see if the results change.
