I don't know what size tires you have but wheels up to the late 80s fit and 16" tires are easier to get and much less expensive than 16.5s if you have them or split rims.

 

Luckily when I got the truck it already had 16" one piece rims on

 

Been a while since I've gotten on...

Since last time I've picked up a decent tire I am 8 lug rim from the junk yard, installed functioning e-brake cables, and converted to DSII.

For the last couple weeks this truck has been my daily driver; 64 miles/day. Been experimenting with timing and gas mileage. 12 BTDC seems to get 11.5 consistently and 10BTDC pulls 12-12.5 regularly. Gunna bump up to 8 if I can next week and see what that does.

 

What kind of gas are you using? Regular, premium or E10 or 15?

 

87 that "may contain up to 10% ethanol." My original setting of 12 BTDC I came to using a vac gauge.
