Would larger tires exacerbate a suspension issue?

Just got falken wildpeaks in 265/75/16 put on my truck this weekend. I had on the stock dunlops in 245/75/16 on before. When I took the truck on the highway yesterday I had some noticeable vibrations. Not death wobble by any means, but uncomfortable enough for me to take it below 70. I've used the shop in the past and theyre very reliable so I wonder if they were balanced wrong or if I might have a ball joint issue or such. Truck is stock. I havent had chance yet to jack the truck up and see if theres any play in the wheels. I also had the trucked serviced at toyota 4,000 miles ago for an oil change and they said the tires were low and my brakes were getting low, so I figure they would have noticed if the ball joints were getting worn, but maybe not.

So has anyone had issues after sizing up or most likely a balancing problem?

 

If it happened right when you switched tires then it's very likely a balancing problem. Changing tires shouldn't have any effect that I can think of on other suspension components in a way that would cause new vibrations.

 

That eases my mind. No issues before the tires. I suppose they need a rebalance. Do you hold any stock that Toyota has a special adapter that properly balances the wheels vs a regular tire shop?

 

I'd just go to a tire shop, I'm sure Toyota would charge you a TON and, as far as I know, they don't have anything special to balance tires.

Discount Tire is usually good but check reviews in your local area.

Also, road force balancing is generally better than regular balancing but it can be hard to find shops that do it. I've had good luck with just normal balancing so it's probably fine either way.

 

Well they were just mounted a balanced about 2 weeks ago. That was my reason for concern. Everythings good til I get to around 70.

 

I had all the wheel weights fall off before I made it to the on ramp after getting the tires balanced one time. Holly hell it was bad .I took it back and not a single weight was still on. They cleaned and let the rims dry before putting the new weights on .

 

most likely a balancing issue. MOST shops SHOULD have the adapter that fits into the LUG holes of the wheel to true it to the balancer. most tire techs are lazy shitbirds who will just stuff whatever cone fits in the center bore, swing the arms and let her rip. slapping whatever the hell the screen says on there.

my advice before you walk on to set the appointment walk up to one of the bays, ask for the lead tech. offer him 20 bucks, a six pack or a small bottle of his choice to make sure the dingdongs in the back get it right. 9/10 times unless hes a scumbag as well, dude will FIND a way to make sure its calibrated, mounted correctly and balanced correctly.

also just for giggles you make wanna start checking your suspension components with a large pair of channel locks. side to side/up adn down play isnt the only way to check for play. sometimes the play isnt felt that way. say for example your outer tierod. its facing in north south direction with litle play forward or back to pivot. it should NOT however bounce up and down in the ball socket of the joint. plenty of times at work ill have someone complaining of vibration or play and nothing is found to be EOL until the Channel locks are whipped out.

i highly suggest checking balljoints (upper and lower) and tie rods with this method.

also when was the last time your carrier bearing on your drive shaft was replaced?

 

That I'm not sure about. Bought the truck last year with 51k on it. At about 70k now. It needs a oil change soon so maybe I'll have them take a look at the suspension components while doing that.
