As promised I am following up to give you my feedback on these vrederstein tire.
I installed 275/40 R20 front
315/35 R20 rears
As recommended in the manual I ran them at 32 lbs on all 4 corners. I really don't carry anything. I check the tire pressures every 2-3 weeks so I am sure tha the pressures were pretty constant.
I installed them on August 9, and removed them on November 11.
I travelled a distance of 17,997 km ( 11,185 miles ) .
I looked at the wear on the tires .
The fronts look to have minimal wear and seem to be very even across the face
The rears however a another matter. There is excessive wear in the middle ( looks like they are over inflated) on both rears and the wear on the rears overall is considerably more than the fronts. ( Ill check the depth in the spring. ).
I travel on highways quite a bit so I would suggest that these miles represent about 70% hwy and 30 % city. I do not think that I will get more than another 20,000 km on the backs. I will reduce the air priessure in the rears to see if I can even out the wear.
Anyone else encounter this situation??
