Tire size question

I have 265/75/16 on an old chevy 1500. The wheels are an aluminum vanity wheel 9.5 inches wide on the seat.
Can I put 235s on these rims?? or 245s??? I would prefer 235s...they are cheaper and a better ride...

I won't recommend that you go against your vehicle's owner's manual or tire recommendations. But... you can mount many different tires sizes on the same rim. The big question is do you want to? It sounds like you are OK loosing tire width. I would make sure to offset with aspect ratio so the tire height, revolutions per mile are about the same so your speedometer remains accurate. As you go narrower on the tire you'll need a higher aspect ratio to end up with a tire of about the same height and revolutions per mile.

As for your comment about 235's being a better ride than 265 I've never been able to notice a ride difference because of tire width. I do really notice a difference in the sidewall though. The less sidewall the rougher the ride.

I would call a tire store and ask - there are charts which list what width tire can go on a certain rim. Keep in mind, you will need to significantly increase the sidewall percentage in the narrower tire to keep the height, and therefore the speedometer and odometer the same.

You have a truck, not a car. Truck tires selected must be able to carry the design load weight.
