John, Here are two sites I find helpful: Tire Size Chart: http://pages.cthome.net/earlycuda/tire.html Tire Plus Sizing: http://www.eunos.com/tirecalc/ Using these charts it looks like the D70-14 should be a P205 x 70 x 14 Coverting to a 15" looks like 205 x 60 x 15. I have used these charts many times and have them bookmarked. I cannnot tell you if the Stock Spirit chassis can handle them.
