No, the wheel and tires should both be straight at the same time.
There will need to be an alignment done on the vehicle to straighten the steering wheel properly. The adjustment to make it straight is called a "toe Adjustment". If it pulls while driving causing the steering wheel not to be straight it will need a Caster or Camber adjustment or all of these may need adjustmnet.
When you have the front end aligned the mechanic should align the steering wheel also. This is so the steering wheel is positioned straight when you're driving straight down the road.
A wheel alignment is what syncs your steering wheel with your wheels. It ensures your car will drive straight when your steering wheel isn't turned.
You probably need an alignment.
The most effective and accurate way is to take it to a local reputable auto repair facility that has an alignment rack. Have them do a complete alignment. Your steering wheel should be straight after.
Take it back to the alignment shop and they should re-do it for free. If you paid for it, your steering wheel should be straight.
I'm not surprised. Go to the alignment shop and get a wheel alignment. It will cost about $80 US. Unless you damaged some of the steering components. It's your ONLY option.
Uneven tire wear. If the car "pulls" to one side or the other. If the steering wheel is not lined up properly when the car is pointed straight ahead.. BBA
Have the wheels balanced. Get a 'front end alignment' done on your vehicle.
A good and accurate front-end alignment.All the parts of the steering and suspension "point straight down the road" will establish the steering wheel to do the same.Anything out of alignment will pull/push the wheel(s) in that direction.
This means something is out of kilter in the alignment or steering itself. The adjustment/repair is not at the steering wheel only.
You have to adjust the tie rods ends between the steering arm and the power steering gear, just make sure your wheels are set straight ahead, and that you don't have any alignment problems. If you don't want to do this on your own take the Blazer to your nearest alignment center and have them center your steering wheel.
