What is the width of original rims, 6 or 7 inches? And what is the maximum tire width that can go on them. I have 205 on there now and it doesn't seem to be able to go much wider.
Here's a link to something that might work...These are original styling but 15 x 8. I think someone wrote on here once that you can put 235 width on those and that would probably be the widest you'd should go on these vans (in the front anyway, and without modifications) due to the suspension and steering stresses. I can't find where I read that though.
