Tires BRIDGESTONE or SUMITOMO

I run S21s on track on an SV650 and they are excellent!!! The S22s are better but both are perfect sport/street/track tires

I had the S22 on my first trackday, also my first time hypersport/sport tires. They were amazing for my tuono 660 Factory. Super sticky and I never felt that I was running out of grip, always had more than enough.

I just ran my 23 zx6r on track yesterday with the stock s22 on it and they work great. I was running 30 psi rear 33 front and they stuck great and I had no complaints.

Run S21 (2.2bar front/ 2.1bar rear, cold)on CBR600 1998, intermediate+ level , nice wearing, quiet hard rubber so i can make 8 track days with rear and maybe 12/14 track days. They become a bit slippery when reaching wearing limit, but still manageable.

I had them in my r6 and they were sticky enough and confidence inspiring enough to let me reach mid-intermediate pace on my first day out. Great tires.

S22 are the lords tire. I used them through intermediate group and it’s the only tire I’ll ever use on the street

Bridgestone weather peak is far and away the best all season I've used. Good in the winter & a solid daily driver tire the rest of the year.

I bought a set of the new Bridgestone Potenza Sport AS and going to be installing them shortly. I’ll update here over the next several months through winter and back into summer on how they do.

Once I got a chance to try them in the rain, I realized there was a problem compared to Michelin. I was fishtailing all over the place on a wet road. That’s never happened to me with Michelin.

These are my winter tires in Michigan. Seasonal roads only, they suck otherwise for off-roading.
