Has anyone tried these? Just wondering how they comapre to OEM runflats and/or conventional tires.

Thanks.

 

The 050s are highly regarded by some folks. I asked Alex about those at one time and not enough had been sold. I believe they are second gen RFs.

There is one person here who has them in Germany, I think but I forget his name at the moment. Maybe he will throw his opinion in but I think he liked them.

 

Thanks, chowhound. The wear rating is listed at 140AA, which I am assuming is a typo, cuz that's real soft.

 

No thats right. Soft compound. Look at the ratings at Tirerack. Its right up there with the Eagle F1s (at least the non-RFs). There is not enough sold of the RFs to have reviews yet.

 

Wow. That seems way too soft to make sense as a street tire. FI GS-D3 is 280AA.

 

I have absolutely no experience with the Bridgestones. My Mini came from the factory with Pirelli Eufori's on it & I loved them. I highly recommend them if you are looking for a performance RF

 

Take a look at these babies http://www.tirerack.com/a.jsp?a=EZ3&url=/tires/Spec.jsp&make=Yokohama&model=ADVAN+A048&tirePageLo cQty=

OEM tires for Elise. 5K miles and its time for new tires

 

Mine did, too. I'm not a big fan.

 

Krikey!

 

This is correct. The new BMW 3 series comes with these tires and they are a 140AA tread rating. The Pirelli Euforias that came on my MINI were a 180 rating.

 

The UTQG treadwear rating is not a durometer rating, but a marketing number that is not directly comparable between manufacturers. Since there are no penalties for having too low a rating, many high performance or competition tires are rated far lower than they could be, just to provide the impression that they are soft or sticky. Perceptions are important for marketing--just look at all the family car tires optimistically rated at 600 and competition tires rated at zero.

The rating system is supposed to work by comparing tires to a government "reference tire" on the same car in Texas (see 49 CFR 575.104). That tire is arbitrarily rated 100, and is fairly representative of the best tires around when the UTQG system was first mandated. I remember regular car tires rated at 50 from back then, and they were definitely not sticky. A 600 rating means the manufacturer believes it will last six times as long as the reference tire, and zero means it should last infinitely shorter.
