What is the Best All-Season Run-Flat Tire? Our Tests Will Tell You!

Wednesday, August 29, 2012 by Doc Horvath

Nearly all cars that come with high performance run-flat tires use a summer only rubber compound to maximize grip levels and make the most of the car's power and suspension. While strong on performance, nearly all summer compounds are short on durability. Many of the customers I deal with are willing to give up a little high-speed performance for more mileage, so they opt for an all-season compound. We recently tested four of the leading high performance tires that maintain run-flat capability to see which one is considered the best.

The four tire manufacturers we tested (Bridgestone, Michelin, Pirelli and Yokohama) are globally recognized for offering high quality performance tires, so we put each model through a series of tests, both on our Real World Road Rides and on-site test track.

At the track, the Michelin Pilot Sport A/S Plus ZP led the way in wet traction and came in a close second to the Bridgestone Potenza RE960AS Pole Position RFT in our dry pavement runs where we simulate abrupt emergency avoidance maneuvers and other situations. The Pirelli P Zero Nero All Season Run Flat came in third with the Yokohama AVID ENVigor ZPS close behind as it didn't provide the same level of grip as the others.

Our Real World Road Ride consists of a 6.6-mile loop of two-lane roads, four-lane roads and expressways, as well as surfaces that include asphalt (some very smooth areas while others are patched) and concrete (complete with expansion joints and some studded tire wear) that are similar to what our customers can expect on their daily commute. Out on the road, we found the Potenza's new 3G technology can minimize the expected harsh ride that run-flat tires are known for and set the bar very high for all the others. The Pilot Sport A/S Plus ZP was just a step behind but both the Pirelli and Yokohama options seemed to transmit the noise and road feel from bigger impacts and expansion joints.

For a complete report of the test, take a look at "Testing Performance All-Season Run-Flats."

Whats the second best run flat I have bridgestone for my 2011 Rav $

Joe,
Unfortunately Toyota is using a tire size that did not normally come in a run flat option, so the only two tires we can offer are the original equipment Bridgestone Dueler HL 400 or the Bridgestone Turanza EL 400-02 tires. We would not expect any other brands to offer replacement tires for some time. Sorry we could not help further !

I am trying to find a high performance RUN-FLAT tire in these sizes: 245/35ZR18 on the front, and 335/30ZR18 on the rear.
Thanks.
I have no spare tire. If the above tires are not available in RUN-FLAT, how can I fix a flat-tire until I get to a service station a hundred miles away. Is there a Fix-A-Flat that really works? Or another way?

What is considered the best/quietest run flat for my 2005 awd Sienna?
Tuesday, September 24, 2013 by Doc:
Ross,
Since all run flat tires have the same (reinforced) sidewall, there is normally not much variation across the tires available in your size in terms of comfort or road noise. If I had to pick one, early feedback on the Pirelli P7 All Season indicates it may be our best option.

Veldon,
Unfortunately none of the 17 tire brands we carry have a runflat option in 33530R18. As an emergency tire repair option, consider the Continental ContiComfort Kit at this link; http://www.tirerack.com/accessories/detail.jsp?ID=38&category=Tire+Inflation&affiliate=FH3

I don't seem to get many miles on my run flats for mt 2007 mini cooper s convertible. Ii had pirellis on there and the inside tread wore very quickly. What do you suggest? They are too expensive to keep replacing. I was looking at the Bridgestone RE960AS or Continental procontact.

I have BMW Z4 Bridgestone run flat
I don't like the noise and stiffness
thinking of Michelin Pilot Sport A/S3
(all season...not run flat)
I realize BMW does not agree with "ordinary" tires in case of a flat etc...but I have not had a flat in 20 years!!! now I will get one !!!
comments or stick with what you have?

Ron,
We have had countless BMW owners switch to non run flat tires with great success. As long as you have a "flat tire emergency plan" like joining AAA or adding towing coverage to your insurance etc, we would not have a reason to talk you out of switching.
