Our Touareg came with 255/60-17 tires from Dunlop. They were throw-aways well before 20K miles. The corners wore off quickly and they became very noisy. This is with the tires inflated to their maximum suggested cold pressure. The replacements were the same size, but from Goodyear. They, too wore the corners off in about 20K to 25K miles and became noisy. Again tire pressure was maintained at the top end of the cold pressure range. The third set was yet another manufacturer and the same size. Same story.
So, for tire set #4, I went to the alternate size 235/65-17 and bought the Generals. It was my guess that the wear problem was suspension related relative to the tire width. These narrower profile tires were better in snow, wet and hard pack/ice. They handled just fine on a 5000 pound truck, but not quite as responsive as the wider, lower profile tire. They've been more than acceptable for towing (5000# fully loaded car trailer) and fine for City/Highway driving. Further, they've been far more comfortable and quiet throughout the 40+K miles so far.
We've gotten more than twice the milage out of these Generals than we got out of any of the previous tires. The product is excellent, but the change in tire profile is what has saved these tires. They aren't as wide and haven't sheered off the corners at all. Treadwear across the entire face is very uniform.
So, if you own a Touareg and are fed up with tire wear, noise and harsh ride, consider going to the taller, narrower profile. There's not much downside and the improvement is very good. Further, the speedometer is spot-on accurate with these tires compared to the original lower profiles. I gave the Altimax Generals mostly 9s with a couple of 8s and 10s. These have by far been the best tires yet in about 120K miles of driving. They probably will see us through the Summer and Fall, but will be replaced before next Winter.
