Tire question on Tundra

[msst8dawgs]

First off, I know this question has been asked 100's of times in a thousand different ways, which is partly why I am so confused. I have a 2007 Tundra TSS with 20" enkei wheels. I hate how much room is between the top of the tire and the bottom of the fender, but never did anything about it. I now have to have new tires and figured why not fix my only dislike about my truck. I called a local shop that customizes trucks basically. He said if I raised the front to level then I could run 275/65/20 or 285/65/20, but the stocks are 275/55/20 so the 275/65/20 will only be wider correct?

And the 285/65/20 will be wider and just slightly taller?

Would love to know what some of you suggest.

Thanks in advance

The 275/65s will be taller, not wider. The first number, 275, is the tire width in mm. The second number, 65, is a percentage of that width and gives you the sidewall height, so it would be 275*65/100. To get overall tire height, you then multiply the sidewall height by 2 and add that to your wheel diameter in mm. Then divide by 25.6 to get inches. But tire height really depends on the manufacturer, since its a pretty suggestive number and depends on where they measure from.
