Tires and wheels effect warranty

Stock wheels 18" tires 265/60/18, new wheels trd 17" 265/65/17 tires, will this effect warranty.

 

Unless you do something drastic like a tire change(size), you shouldn't have any issues. Going up a rim size from 17" to 18" isn't going to do any harm, unless they were installed wrong. You're good to go.

 

Thanks for reply, Looks like 265/65/17 is a stock tire on the tacoma so like you said I wouldn't think it should be an issue.

 

As I understand it they have to be able to prove that your alteration caused the damage or at least a direct relationship to the damage to refuse warrantee coverage. So a nitrous kit and a blown motor you're probably fucked, tires and a blown motor you're covered. This is initially up to the dealership and I've heard of warrantee cases going either way, but if they refuse service you always have Toyota to go to and get it taken care of.

 

Ditto.

Changing the offset or adding wheel spacers changes the angular load on the wheel bearings and could be used as a reason to deny warranty coverage for them. They also increase the side loading on the ball joints, but I've never heard of it being an issue.

Lift kits will absolutely be used as a reason to deny coverage for the CVs and boots, as well as vibration issues, and wheel hop caused by axle wrap.

Oversized tires are where it gets really dicey.
They increase the load on the brakes significantly. Short pad life or problems with warped rotors? Likely on your own.
Without regearing, they are increasing the load on the engine and transmission, and could be used as an excuse to deny coverage for transmission slippage or damage caused by transmission overheating.
Regearing will reduce the likelihood of failure, but may not change the service writer's opinion of whether or not to cover it.


Frankly, I just don't get it, why service writers seem to try to deny warranty coverage. It makes for a happy customer, who is leaving in a safely repaired vehicle, and who tells his friends how good Toyota treats him, and the dealer is guaranteed to get paid for the job.
Sure, they can make MORE money on a non-warranty repair, but when they tell the customer that it's going to cost $800 to replace their rotors, people like me will tell them to take a hike, go to the parts counter, spend $300 on a pair of rotors and pads, and have the job done before bedtime.

It's like it's a TSA power trip thing. They have the authority to make someone else's life difficult, and dammit, they're going to do it even though they don't have to.
My last supervisor was like that.

 

All depends on the dealership, and sometimes your relationship with them. I've seen warrantee stuff done where it shouldn't have been and denied for no good reason. A friend of mine was dumb enough to leave his nitrous system and track tires on his car and take it in for a transmission failure. The quarter panels were still covered in VHT and tire shreds from track burnouts. The dealer warranteed the trans then told him he should take the system off if there's ever another warrantee failure. That dealership became well known in our racing circle as the place to go, Ford bought lots of repairs for drag racers. I don't remember which dealer it was.
