But I checked mine with GPS, so I'll bet mine's close enough. I posted an earlier reply to the post above Rock's. Not sure where it went... John B. Re: 33x12.5 x 15 inch Tires for my 89 swb v6?

I broke down and bought FIVE 33x12.5 Duratracs for $895 I'll post some photos after I get them mounted. All right - I guess I should have said how much worse is your MPG with the 33"s Whats the gearing/ratio of OEM #4625 axles Last edited by Bubba; 12/14/13 09:11 AM. 89 V6 SWB OEM Sunroof RPW Headers & Custom Exhaust 15" Toyota 4Runner Chrome Rims 33X12.5 Goodyear Wrangler Duratrac Stainless Steel Lugs 85 2.6 Montero (RIP) <img src="/forums/images/graemlins/frown.gif" alt="" /> Re: 33x12.5 x 15 inch Tires for my 89 swb v6?

All right - I guess I should have said how much worse is your MPG with the 33"s Whats the gearing/ratio of OEM #4625 axles Nice price. Not sure. Also depends on the current mpg and engine/drivetrain condition. Don't forget to compensate based on the larger tire diameter for both the mpg and maintenance mileages. Also you can improve the mpg by swapping to a 90-91 transmission with the lockup torque converter. 89's didn't get them. Ratio of that r&p is 4.625:1 Re: 33x12.5 x 15 inch Tires for my 89 swb v6?
