Just got a set of BF Goodrich Silvertowns, 500-15 bias ply from Coker for my wifes coupe. I took them to the tire shop and had them mount them on a set of Fenton Gyros, 15" x 3 1/2". The problem I am having is that the tire will not seat completely on the rim. If you look at the pictire from the side the white wall is less on the top than on the sides and bottom. In fact, it makes the tire lopsided and out of round (second picture) to the point that they could not be balanced. The tire shop told me to put in 80 psi of air and let them set. He said this will stretch the tire and basically make it round to the rim. I have had these setting with 80 psi of air in them for a week now and neither of them have moved. My question is has anyone else had this problem? I have bought about 5 sets of tires from Coker and have NEVER had any problems. The rims are in brand new shape so I am pretty much counting them out as a problem. Could it be the tire? I just wanted to ask of anyone else experienced a problem like this before I call Coker and ask for ***istance. Thanks for any info/suggestions someone can provide. Flatheaded
Have you done a lot of business with the tire shop? It looks like they weren't mounted right. And it seems odd to me to put 80psi and let them sit. I wouldn't think the tire would stretch more with the same amount of pressure in it. I'd have them remounted with mounting paste instead of lube. just my .02
i would #1: call coker. #2 get a different tire shop. i don't think 80 psi is gonna stretch out the tires bead in 100 years. it certainly ain't gonna do it just sitting there, you'll at least have to break the bead and try to reseat it. i'd measure the rim and tire. and don't ***ume the wheel is good just because it looks new, lots of New Old Stock has achieved the "Old" part because it doesn't fit right.
I agree with ray about the rim. It won't be too much h***el to dismount the tires & measure the rim diameter. If the bead is 15 inches then it's the tire. I used to get some that wouldn't seat and I would bounce them a few times like a basketball. If they don't seat then, they need to be replaced.
Thanks for the input guys. I too didn't think just by letting it sit with 80 psi in it would stretch it enough. I've been doing business with the shop for about three years but think I will try another shop and see what they say. I also tried to bounce it on the shop floor. Used to get cycle tires to seat this way but it too didn't work with these tires/rims. Thanks again for the input. Back to the tire shop we go! Flatheaded
