Vibtation problem revisited, It's all in the tires

[Bouma]

I posted last week about a vibration in my truck. After 2 days in the shop here is what I've got. The tires ballance!! BUT they are out of round?? Dosen't make sense to me but 2 different shops came to the same conclusion. Now I have an appointment with Goodyear on Wednesday to look at my tires and (hopefully) give me 4 new ones. I have the Goodyear Wrangler Silent Armor tires. They have a 50,000 mile warrenty, the tires have 13,000 on them and are 65% gone. This is according to Goodyear. I took the truck in today but customer service is closed so we will do this Wednesday. The question is, if they give me 4 new tires this is a dead issue. The manager seamed to think they would only give me one maybe two. They won't pay for mounting ballancing and all that crap either. So if I have 65% of my tires gone can only get one or two tire and then pay the cost of mounting and ballancing do I just go with something else?? What tires would everyone recomend? I drive 90% or better on the highway and in town. When we get a snow storm thats when I need to pull my 29' snowmobile trailer. Snow traction is a very big thing to me. Toyo? BFG? Firestone? etc. Please help!!
