- 85 series tires on Tacoma?
- Posted by Sailor
I'm getting tired of putting gas in my 2002 Prerunner, 3.4 V-6 A/T.
Since it was new, 85,000 ago it has gottten 16 mpg in town.
I'm thinking of putting 215 x 85 x 16 tires on it and try for a little
more mpg.
Just wondering if anyone has done this, and the results.
The narrower tires have to roll a lot easies.
Also wondering if the stock width rims would be Ok with the 85 tires.
Any users out there?

I went to 30X9.50X15 and 8" wide wheels from the 31X10.5X15 and 7" wide
wheels on my 3.4 v-6 A/t '99 Tacoma with very little change in gas
mileage. The in town mileage is now 16 to 17 whereas it was 15 to 16.
It does drive a little better, I.E., smoother acceleration and better
braking. The highway mileage is about the same. (both corrected for
odometer error) I think the higher ground clearance of the Tacoma 4X4
and Prerunner causes drag that has more effect on mileage than changing
tire size up or down one or two notches. The 31's measured 30.5"
diameter with 8.5" tread width and the 30's are 29.4" diameter with 7.5"
tread width.
This tire size calculator might help you decide what to do-

around $200.00 for the electronics to correct your speedometer/odometer
you will have to live with it. http://www.fmdkinc.com/wiz.htm Toyota
does not offer any fix for it

The only thing I can think of is that the v-6 is not working as hard.
According to a mechanic friend the bigger tires can and do cause
problems unless the gear ratio is changed to keep the engine in it's
power range.

Be sure you keep the tailgate closed, especially on the highway. Open
tailgates or those pre-runner-type fish nets will reduce your MPG.
Probably not a big difference, but at today's prices, every little bit
helps...

Speaking of poor traction, I always have to laugh when I see a show
about a diesel Dodge, GM, or Ford pickup with a Bully Dog or other power
adder system. They can't help but show the thing doing a tire boiling
burnout (usually the right tire only) as if it's supposed to impress the
viewer. I think to myself, 'OK, you just proved the thing has crappy
traction, what else can you show me?'
