I've got a question about tire performance on my '01 4x2. I'll try to make it short but it takes some explaining. Within the last year I replaced the upper and lower ball joints, front and rear shocks, bearings, rotors, brake pads and one spindle after I damaged the threads. All this was followed by a new set of Uniroyal Laredo's and an alignment.
Initially I felt the ride improved over the worn out tires that were replaced. However, the tires did not ride as well as I was hoping but figured it was never going to ride smooth like the wife's minivan. After the first rotate and balance I noticed a rythmic bounce from the rear end when riding at a constant 49mph and again around 65mph when running on a smooth road. Over the next weeks I went back to the shop four times about it. The first three revisits they rebalanced the tires, did a 'road force' balance, and spun one tire on the rim before rebalancing all four. On the fourth visit the shop foreman road with me and said it was bad tire. Great I thought! When I picked it up they said they 'measured' all four tires and 'replaced the worst one'. They said the tread was 'running in and out' and that was what I was feeling. The 'bounce' improved alot but I can still feel it get into a rythm just under 50mph and again at 65mph.
Is there anything, other than tires, that could cause what I describe as a 'rythmic bounce' when driving at certain speeds? 49 and 65 seem to be my magic speeds. I'm no truck tire expert and I've purchased multiple sets of tires from these guys over the years, so I'd like to know if there's any other possible reason for feeling this. In all the return visits to the shop they've never said there was anything else wrong with the Trac. I'm trying to decide if it's easier to take a loss and replace the tires at my expense (from a completely different retailer) or keep going back to the place I bought the Uniroyals to see if I can get somewhere.
Thanks for any advice!
