Used tires on new truck

ive got a 2015 prerunner sr5 and just acquired some take offs of a 3rd gen.

I just put them on the truck yesterday and I noticed the truck is pulling to the left.. do I need to go for an alignment?

The guy that took them off didn’t mark the tires so I don’t know if that’s an issue..

 

Probably needs an alignment.

 

i'd say alignment. maybe the old tires "adapted" their wear to the bad alignment. I'd also check to make sure you are seated properly against the brakes. I always torque mine down in a cross pattern to make sure they're seated right.

also double check that the shop didn't leave any nuts off or loose, that happens a lot it seems.

 

I installed them myself and tighten the lugs down in a cross pattern.

It’s raining today, so I’ll check air pressure first then go see about an alignment. Didn’t wanna fork out money

 

sounds like it was already out of alignment.

 

No.. I took my rims/tires off and swapped them with his takeoffs.
Truck didn’t pull none the entire 3 hours round trip to pick up his takeoffs.

 

Are they the same size tires/Wheels?

 

I went from steel rims to alloy 3rd gen rims..

Tires are the same brand and size

 

Shouldn’t need an alignment if you swap same size tires/wheels unless it was already out. My bet is it was off a bit and the new tires brought it to light. I’d have it aligned and bet it goes away.
