MPG's and 29" tires

Featured Replies

Anyone calculated your MPG's with 29" tires? Just wondering what your getting.

I get about 22 mpg or so... sometimes as high as 24, not usually lower then 20. I was getting 32 unlifted... 87 EA82 carb swapped to SPFI MT5 D/R 3.9

With 30x9.50x15's and a weber, I get in the high 20's 27 or 29MPG.

Not if you get a Weber and put on it. It's like Night and day.

I don't think so, Spfi is a whole nother deal. Spfi is good, but you can't really convert that to well. If it was carbed you could do it pretty easy. But I think there are less problems with SPFI. I'd stay with that.
