Best Run-Flat Tire? Perhaps the Bridgestone Potenza RE960AS Pole Position RFT

Wednesday, March 7, 2012 by Hunter Leffel

Bridgestone's 3G RFT Technology is designed to offer almost the same riding comfort as conventional tires and that's why the Potenza RE960AS Pole Position RFT may change the way you feel about run-flat tires.
 

The biggest enemy to the tire when running "flat" is the heat generated. This traditionally has required a thick, stiff sidewall to move the heat off the tire to prevent failure. A thick sidewall results in the unpleasant ride qualities most people associate with run-flats. The new 3G RFT Technology uses protrusions or cooling fins on the sidewall. Bridgestone also molded a NanoPro-Tech Sidewall reinforced rubber compound into the tire's sidewall. These two features reduce heat generated and aid in moving the heat away from the sidewall. This allows a reduction in sidewall stiffness, which results in a more comfortable ride.

  • Improved ride comfort and wear
  • Balanced all-season and dry performance
  • Dual layer tread compound that changes to maintain wet traction as the tire wears

During our test of the the run-flat and non-run-flat version of the Potenza RE960AS Pole Position, we found the ride quality and noise from impacts to be similar, with the advantage still going to the traditional tire. However, the tread pattern and compound are shared between the standard and run-flat tire and the gap in qualities has shrunk. Overall, we felt the two tires were very similar, which is in stark contrast to past experiences with run-flat tires.

The Brdigestone Potenza RE960AS Pole Position RFT is available in the 245/40R18 size If you have the 225/50R17 then I would consider the Yokohama Avid Envigor ZPS or the Pirelli PZero Nero All Season RFT.

I have a Mercedes CLS55 with performance package, which deletes the spare. Tire sizes are 255/35/19 and 285/30/19. Would like to get runflats for safety, but ride comfort is an issue. RE960AS RFT comes in 285/35/19, which should fit in rear wheelwell, but it doesn't come in 255/35/19 or 245/40/19. There are other (summer) RFTs in correct front size. Is it ok to mix summer front with all-season rear RFTs? Any recommendations for the most comfortable 3G RFT in 245/40/19 or similar?
Thanks.

hi,
In thoe sizes we recommend for your car,i am afraid the run flat options are quite limited and will result in perhaps undesireable ride harshness.

Still feel the 960's are the best runflats you sell? Still 3rd generation if I buy now or is it 4th generation. 245/45/19s for BMW X3 awd SUV
