315/85 22.5 steer tires???

I am currently running 295/75R22.5 tires on 22.5 x 8.25 Hub steelies, but they are ripe... ...they are original equipment (bus has 26K mi).

I am easing into this painful expense by getting the Alcoa rims now and wanted to run a 315/85 22.5 for steer tires, which means I need a 9" rim up front.

It'll all work mechanically, just wondering if it'll fit & if anyone tried this on a TC2000 or can talk me down from this ledge???

I did find the coolest tire calculator: https://www.tacomaworld.com/tirecalc....5-315-85r22.5

Not sure what your current situation is in front, but be sure to confirm that the wider tires will clear everything at full lock.

That is the kicker, Tango- you don't know until you buy them and try.

The dump truck guys run those bigger wheels up front.

Worst case scenario you can always re-set the stops. Best of luck with it.

I refitted a few of our trucks Petes and Freightshakers w/315's so as to be legal on front axle weight from 11 22.5s and had only sleight clearance issues on full lock to lock barely rubbed springs on rear of front outer springs I would think it should not be an issue but axle geometry might be different on a skoolie.

Another consideration is that steering component wear is acclerated by the wider flatter imprint of a 315 over an 10 or 11 22.5 so unless you need the additional weight carrying capacity of the 315 I probably wouldn't do it.The wider footprint can also cause wandering if the axle wasn't designed for them.

Thanks- I might loose a tiny bit of turning radius, but looks doable (fingers crossed). I'd really like the extra bit of tire under that heavy front end.
