Dear Truckin'
I just purchased Vol. 36 #5 and was reading the tech article on your 2009 Dodge Ram titled "Booming Tunes". What brand of sub box did you use?

Lee,
We asked Joe at Audio Innovations in Glendora, California, where we photographed the install, and he said the company that built that enclosure is no longer in business. However, Subthump also makes a box for the new crew cab Ram, you can find them at subthump.com.

Hello,
Your mag is great, I just noticed something in the current issue with the white Chevy on the front. In the "Double Duty Dualie" article it says he has 22.5-inch wheels but nobody makes a 22.5-inch low-profile load-rated tire, is that just a misprint or does Sumitomo make a 22.5 low profile tire? If they do, I'd like a set for my square body dualie. Please help and keep up the good work.

Bryan,
Good catch. The wheels on that truck did start off as 22.5-inch big-rig style, but they were machined down to accept 22-inch tires. Although tire makers don't recommend going to a lower load rating than was originally equipped on the truck, the Sumitomo tires are rated for a load of over 2,000 pounds each. So while towing capacity would be reduced by not having load-rated tires, the truck still has plenty of capability.
