So ordered a 25x8.5-14 R14 from the dealer. I repeatedly said the tires were R14. After driving over an hour to get to the dealer, what the dealer actually got in was an R4 by Carlstar their Ground Pounder 400. Initially I was going to refuse the R4 and the dealer went back to see if he could get the R14 to which he told me that R14's had been discontinued. Really? So I looked at the R4 and it seemed like a heavier built tire so I went ahead with it and ordered a second one for the front so the fronts would match. I weighed the R14 and it weighed 24lbs. The R4 weighs 32 lbs. That's an 8 lb difference on a 25" tire. The R4 is a much stouter tire than the R14.
I'm thinking about going to R4 on the rear tires also. The rears are 15-19.5. Anyone have any experience or onions on the Carlstar (formerly Carlisle) Ground Pounder 400's?
