RE050A vs. RE750 - E28 M5?

[Cory]

What might be the comparison of the Bridgestone Potenza RE050A Pole Position and the Bridgestone Potenza RE750 for an '88 M5 on dry conditions most of the time. I'm interested in ride comfort and treadlife while maintaining a sporting nature - it's more of a Sunday driver than anything. Any other recommendations would be appreciated. I wonder if the Yokohama ADVAN S.4. might be worth a look, too, or something like that.
Thanks.

I had the RE750s on my E36 M3 and loved them. Great grip, tread life seemed to be forever (on a daily driver)!

I'm on the 750's they grip great...heat up fast you can actually see blister on a hard driving on the streat...very good tires...lasted me 22k miles on hard street driving....

RE050As are a max performance summer tire. They have a treadwear rating of 140. You will burn through these. Probably about 12-15K miles.

RE750s have a treadware rating of 340. Much longer lasting. And still a High performance summer tire.

Note that neither tire is really suitable for driving in winter. I run S03s on my car (which has now been replaced by the 050s). They are manageable in dry conditions in the winter. As soon as it gets around freezing and wet out they become a handful.

Neither tire is going to be too comfortable, especially at the pressures you will likely run (a friend with an E28 M5 runs around 40lbs in his with 17" AVS Sports).

The Yokohama Advans are VERY expensive IMHO.

Cory - you should look at S03s as they are still a great tire and are cheaper now that they are sort of discontinued. You should also look into the Goodyear F1 GSD3. They won a recent comparison in Car and Driver which included the 050s, Advans and PS2s. Great all around tire and excellent value among the "big" brand high performance tires.

fwiw, the REO50As tested by car and driver were not the pole positions which are much different from what I understand.

The winners are the RE750 for the M5 when I go back to the original wheels and the ADVAN S.4. for the M3 when my RE050A's wear out. Just sold the Honda Civic and the M3 is now my daily driver, which is hot.
Thanks for the insights.

They are very similar. Both sport 140 wear ratings. Both (when comparing the same sizes) have the same dimensions, weight and load capacities (see 255 40 zr 18 for example). The only difference I can see is AA A v AA UTQG. Which means that both are AA traction, but the Pole Position also has been rated A for temperature, which I'm sure the non-PP is as well.

The readily apparent difference is that the Pole Position is marketed with UNI-T in its name, which is its marketing spiel for wet weather compound. Both versions, however have this. In fact, going to Bridgestone's website reveals that only the RE050A pole position is listed. (As well as the RE050). My guess is that the two different versions available (PP and non-PP) are merely different designations for different distributors so that there can be some disntinction for the purpose of price cross shopping.
