I had a set of 10PR Generals on a '79 Dodge W250: 360V8 w/granny gear 4spd. I ran them at the 80 psi max, mostly empty and I got 18mpg (yay) but the belts shifted and rode like they were square (boo). General replaced the tires with a pro rated adjustment. I sold the truck for pennies on the dollar during the '79-'80 gas crunch after 11 months of ownership.
I got the 10 ply's cause of the amount of towing I do, and the 7000 lb trailer and 750 tongue weight I haul....the 10 ply's are much more stable when I tow.....run 45 front/50 rear.
Great contact patch!Im running 33psi on load e and also seeing weird marks on my tires. I think it's my driveway though. ?
I bet he is talking about the two faint lines
What kind of tire shine is that? It looks awesome.Im running 33psi on load e and also seeing weird marks on my tires. I think it's my driveway though. ?
Saw this article and remembered this thread.I thought the same thing - that OP is referring to those lines. Maybe they have something to do with a QA thing or as a visual reference during the manufacturing process to indicate the tire compound.
A tire company used to provide me with mountain bike tires to test while racing and training. They had different coloured lines running the circumference like seen in the OP’s photos. Sometimes, more than one line. They were used to designate the compound in each of the tires. It was an R&D thing. I would rotate them in and out of my riding and note any difference in handling, wear, traction, etc. and give them back when I was ready for new ones.
Maybe @Colo_Ranger or our friends at @Discount Tire can offer insight into what those lines are for.
Edited: Added pic to clarify what “lines” I’m going on about.
2 faint likes are probably just a different type of rubber. Tires are layer of various materials.
