Did a search and did find some information on wheel size, bolt circle and backspacing, but wanted some feed back before I make the two hour trip to purchase a set of Pro Stars. They are 15x8's, 5x4.75 bolt circle and 4.5 backspacing will I have any problems mounting M/T ET streets 26x10.5x15 and/or radials 245x60x15. These are used and have been told in great condition but if size will be a problem than I will save my funds and buy new next year. I appreciate any comments.
