TRD Pro 17x7 Wheels, with 285/70/17 Tires

I'm curious to hear any issues you've encountered if you're running this combo. I have TRD Pro wheels which are 17x7 vs the 17x7.5 wheel width that is recommended for 285 tires, and the 17x7.5 wheel width is also the size of the factory wheels on a ORP. I have no idea why Toyota would put 7.5 wheels on the ORP and not the Pro?

Here's the issue I'm encountering. I have BFG KO3 tires and I'm having a difficult time getting them to balance. I've had them road force balanced 3 times and I thought the issue was finally resolved until my tires were rotated and the front end was shaking like crazy after. I took it in again for yet another road force balance, and it improved, but it's still out of balance. It was suggested to me that the problem could be due to the wheel width. The 285/70 is possibly pinched too much and it's questioned whether the tire is seated properly on the wheels.

Anyway, I'd appreciate hearing from those of you running this combo and any issues you may have encountered and how did you fix it. Also, what's the lowest psi this tire/wheel combo can be aired down to without risking breaking the bead? Thanks!

 

I ran that size tire and wheel for a while a few years ago without issue. Not KO3's.

When a shop can't balance a tire, get an alignment within spec, can't etc., I tend to find a new shop.

If a second opinion says yup, tires are unbalancable (is that a word?) Then you know it's the tires. If the shop gets them balanced without issue, we'll then it's the other guy.

 

KO2s and KO3s are known to be difficult to balance. I would try balancing beads if I were you. Plenty of folks run 285s on the pro wheels without balancing issues

 

I'm going to the second Discount Tire shop in town and push them to remove and re-install the tires to ensure they're seated correctly, worth a try I guess. Thanks for the input guys.

 

TRD PRO wheels -
(Personal experience)

• I have Toyo Open country 285/70R17 on TRD Pro wheels. At regular tire pressures (34-35psi) playing on snow and dirt doing do nuts I haven't pop a bead. Don't some light offroad with them but haven't air down alot, so can't really say anything.

• I think TRD Pro wheels are American made , probably why they get installed on TRD Pros after they come to USA, may not be as good quality as TRD Offroad wheels / SR5 wheels (what I think). When I got my TRD PRO I had the steering vibration. Did Roadforce balance and it was good.

• Reason for TRD PRO having skinny wheels are because if the offset TRD PRO wheels have. If they use 17x7.5 wheels with +4 offset the tire might be poking out more and might cause they problems with regulations. (maybe...)

BFG KO2 -
(Personal experience)

• I have used multiple sets of BFG KO2 in size 265/70R17 (load C), 275/70R17 (load E), 285/70R17 (load C) on factory SR5 & TRD Offroad wheels. The discount tire near my house didn't have problems balancing them. I have air down KO2s on TRD offroad wheels at 12-15psi and didn't pop the bead.

BFG KO3 -
(No experience)

• From what I see KO3 (even load C ones) are very heavy. So might be challenging to balance.
• From couple of videos I see KO3 seems to be excellent in snow. But the weight is very concerning to me. I mean KO2 LT285 /70 R17 116Q C1 RBL is 50.33lbs vs KO3 LT285 /70 R17 116S C1 BSW is 57lbs.

(please don't argue that common Falken Wildpeak AT3W LT285 /70 R17 116Q C1 BSW is 64lbs & AT4W is 65.4lbs.)​

 

@BoiseG I've been running 285/70r17's on the TRD Pro wheels with no issues for tens of thousands of miles...I've even aired down on fairly aggressive trails with them. The issue is likely not the wheel width, but the BFG tire you've purchased, coupled with the balancing method at the tire shop.

BFG KO2's have a reputation for being difficult to balance, a simple online search will confirm this. I'd imagine they haven't deviated much in their manufacturing process when creating the KO3. I personally went through THREE sets of KO2's with multiple warranty claims, all due to balancing issues. I eventually gave up and moved to Toyo RT Trails and haven't had a balancing issue since (on the same TRD Pro wheels!). I personally would not purchase another set of BFG's due to my past experience...However, there are people on this forum who've had positive experiences with the tire brand...

For a better balancing experience, ask the tire shop to use what's called a "spider plate" or "finger plate" style adapter for Toyota truck wheels, coupled with a Hunters Road Force Balance machine. Ask for them to turn off the "smart weight" system on the machine, and if the road force readout reads above "20" on any one tire, ask for that tire to be replaced. @nimby put together an excellent write up a while back regarding this, see below:

 

Great info, thank you very much guys for taking the time to share your experience. Much appreciated!
