What size tires are on it - 1992 Chevrolet Lumina

Fat as possible.

Many saper tires are not full size and you can replace them with the same rim and tire set up that matches the rest. Please rate if this helps.

The major problem with increasing tire size on the Envoy is at the front wheel assembly. The upper ball joint is very close to the tire, even with standard size tires. Go to www.trailvoy.com and do a search on tire size, I believe someone posted a chart of tire sizes for fit with different years of Envoy and Trailblazer.

Front Tire Size: 225/65R16
Rear Tire Size: 225/65R16

the stock rims should be 16" making the tire size 205/55/16. let me know if you have a different rim size. you can look at the tire size on the tire sidewall and the last number is going to be your rim size. if it's a 15' rim the tires are 195/65/15 and finally for 14" rims the tire size is 195/70/14. hope this helps.

Tire sizes are on the drivers door label.It will have the tire sizes and how much air should be put in them.There might be 2 or 3 different tire sizes.If you put on different tire size then the cluster has to be programmed to the tire size that is on the vehicle so that the speedometer is accurate.Hope this helps.Good luck.

Inside your drivers door when you open the door there is a tag for your tire sizes. You can look at the other tires and get the size that already on the vehicle...235\70\R20. example.. Look for numbers like these
