if i run a 285-75 on my 2004 ranger edge 3.0 with a 3 inch spindle lift how much power and mpg would i lose ?

 

Can't say exactly but you will lose some. It depends on where and how you drive.

 

Also depends on your gearing.

 

im not sure wat gears r in it i think its the 3.73

 

If you're running 3.73s, I'd suggest re-gearing to at least 4.10. I ran my 285/75s on 3.73s for awhile and couldn't stand it. You'll get really good mpgs on the highway, but it'll kill you around town or trying to get up to highway speed.

Running that low of a gear (numerically lower) will put alot more stress on your transmission too. Save yourself from buying a new tranny like I had to do and regear when you put the tires on. I'm running 4.56s now and I love it.

 

ok how much do they cost

 

Around 850 total for parts and labor. I saved a little by buying the ring and pinion and master install kit online and paying a shop to put it all in.

 

crappy mileage. if youre worried about it, dont do it. my 98 4 cyl went from like 290 miles a tank to 230ish miles a tank. i havent regeared or anything though either.
