I have an 87 S-15 W/ a 3.4l GM performance upgrde pushing over 200 horses. Ihad to have my tranny replaced do to distruction. i.e bad rebuild. but now my speedo is off by 20% ( 10 miles equals 12 mile) I have 234 60 r 15 on 15 x 8 4 inches of backspacing.
now the question
1. Will a 295 60 15 be the right tire to correct the speedo? I did some calulating but I'm not sure it is right.
2. does any have 295 60 15 on the front? do they rub? Will they fit. Sport truck had an article but I can not find it.
3. The truck has 272 rear end gear in it. Am I going to have anything off the line or is it going to be all top end.
4. Off subject how do you hook a tach up to the system? My truck is set up just like a 87 2.8L. I may have gotten a bad tach.
Thank you
