JUST PUT ON 275 Drag raidals

[slamming 6]

Does this mess up the speedo because of the hight difference betwean the 245s and 275s,BTW they fit great on 8in rims W/4in rear spaceing

Depends on the complete size of the tire. 275/50/15's are just a tad shorter than the stock tire hiegth but not really enough to throw the speedo off hardly at all. Other sizes will be off a bit as a 275/60/15 I believe is almost a 28" tall tire.

Like BOOSt said it dosen't matter on the width of the tire but the height of the tire measure the tire from the top to bottom if it is 26" your fine but if it is 28" the speedo wont read correctly.

275x60 BFG's will cause about an 8% error....it'll read slower than you are actually going ie. 60 on speedo is really 65
