Hallo Keith.
Michelin TB5 R (road legal Racetires)

Gruß Harry

[Dougal Cawley]

there are choices:-

TB15 intermediate fully treaded road legal tyre http://www.longstonetyres.co.uk/page/michelin-tb15

TB5 F & TB5 R - semi slick road legal tarmac rally tyres the TB5 F has a softer compound designed for use on the front, and the TB5 R with a harder compound for the rear of a rear wheel drive car. (you can use TB5 F all round for hill climbs

There is hope inn the future of building a 285/40R15 Cinturato P7 to go with these http://www.longstonetyres.co.uk/page...i-cinturato-p7

The TB15 is too soft for dry roads. It's now a perfect tire for wet roads. Not under heavy rain, but really nice on the wet. Some years ago, the rubber was harder and the tire could be driven easily on dry roads.

For the F and R compound on the TB5, I tried the set up you proposed (F in front, R for the rear). But the front tires suffered quickly. If you want to use them mainly on open road, I would say R for the 4 tires is the right choice. R isn't a hard compound anyway. The handling is great, especially with the heat. I have this set up now on my Trudi and the wear is well balanced. And on a slightly wet road, the compound and the design of the TB5 R are good enough if you drive carefully.

wait, so the TB5 R is preferable to the TB15 for regular use?

I run TB5's and they work well. Cannot comment on any comparison though. I can tell you they seem to be very sticky. Seems like every little pebble sticks. As for rain, I don't drive much in the wet, but on return from Amelia Island it rained quite a bit and I didn't have any issues. Of course I wasn't driving like a mad man either.

Edit, I don't know if mine are R tires. Just know they are TB5's.

It's easy to check if you have R or F compound: it's printed on the tire! (see my pic)

As I said about the F compound, I had F in front and R on the back for my first set of Michelin. I destroyed the front tires very quickly: about 3000 miles on open road or 2 rallyes like Coupe des Alpes. Ok, I drive fast. But since I changed for R compound every where, it's much better. And I didn't lose anything with the handling, because it's still racing tires and quite sticky. I have now about 5000 miles with my new set and they are still OK.
