I have recently purchased a new Dodge Ram SRT-10 with Pirelli tires on it. At about the 5000 Km mark a slight shimming was starting to develop at 110 to 120 km per hour. The vehicle was brought back to the dealer where it was purchased, for tire balancing. A road test followed but shimming still present. A different dealer was used (with road –force balancer), more balancing was done (4 balancing at 3 different locations and shimming still there). The rims were spun for run-out, no defects were found (all rims OK).
The only other option was to contact a Pirelli rep to discuss the problem. An appointment was made to meet the rep for more balancing and more road tests. After examining the tires for abuse and proper inflation he noted that the tires were under inflated by 1(that’s one (1) pound), right then and then I knew this was not going to end well. I explained to him that the distance traveled to get there was less then 3 km, not giving the tires enough time to warm up. After seeing the tires spin on the balancing machine, it’s very clear that 3 out of the four tires on the balancing machine have a wobble on it (one of them with a hop). No instrument was used to see the severity of the wobble, only his expertise to determine that the wobble and the hop is within specs. His final decision ……no problem with the tires.
The tires were mounted back on the vehicle, and preceded with the road test. He sat in the passenger seat my 8 year old boy in the back (been a quad) and I drove the vehicle. As we proceeded to the closest freeway he noted that the acceleration used to bring the truck to freeway speed was excessive (strike 2). At 110 to 120 Km the shimming starts, he reaches over to feel the steering shimming but notes that the grooves on the road might have something to do with it. We proceeded further down the freeway (where the road is freshly paved) with more shimming to follow. He is refusing to acknowledge the fact that his perfectly balanced tires are reacting in this manner. We drive back to the shop where we originally started this ordeal in which his final word stands ………..no problem with the tires….One question here ….is this guy working for Pirelli ? Or for the competition?
To my opinion this guy has succeeded in his goal …….preventing me from purchasing another Pirelli tire for as long as I live.
