Ok I have a question on what to do. Today I must have run over something on my 14 Ram laramie cc 1500 4x4. One tire started losing air fast. I took it to a local repair shop who repairs tires and wanted a patch repair which they do. Well after 20 min I was told my tire was junk. I guess it cut the cords and is un repairable. Now this is the second time with these tires in 27,000 miles I've needed to repair a tire with road debris. Maybe it's bad luck or is it the tire design? Anyhow my question is with 27,000 miles on my stock tires can I replace the bad one and be ok or will it throw things out of wack? My tires are half worn and in good shape for at least another 20,000 miles. I rotate them every 5000 miles. Repair place says putting 1 tire on will screw with the 4x4 system. Should I bite the bullet and get four new or replace the one. If I stick with the stock goodyear wrangler 20 in tire they are $775 and if I go to a general grabber they are $855. I like the way the stock tires handle but this is the second tire problem I've had with these tires. Any input would be appreciated.
