Hi. Got caught up a bit & looked at my tire catalogs for both Coker & Diamondback & both offer the 16" radials in both 550R/16 and 600R/16 sizes.
As my coupe is a bit higher in the front I should be able to put the 550's in front & 600's in rear to level it out. But first I need to get the engine rebuild finished on the 235 & get it installed to see how it stands then & decide on what radial tire sizes to order.
