im new to this forum...so here goes..

My stock car tire is 26 inches tall, rim and rubber. What is the biggest size i can safely put on my car?

We haven't test fit anything larger then the stock size on this car. We have test fitted 225/55-17 (26.7" overall diameter) on the 1992 Olds 88 Royale LS which is based on the same chassis so a tire of this diameter may fit.

If you're running stock 15x6 rims, the closest fit to a 26.7" tire would be 225/70-15 size which has an oveall diameter of 27.4 inches.

Given that we have little information on this car, I would recommend looking at the Buick section of this forum and Buick specfic forums to see what Lesabre owners have run EG www.lesabrenet.com

Thanks for the reply, but the link isnt working right...could you try again?

If anything else helps:
1992 Buick LeSabre 4dr.
Stock Rims

Dont know of anything else i could add...and i will check the other forums here.

Here is the correct link:
