Towing Question

I’m not an expert on towing and don't tow much these days but I think my Suburban had a higher towing capacity than the H2. Assuming that’s correct, is the weight of the H2 the reason or is something maybe undersized?

I believe that the reason that the H2 (with the same engine, rear gears, and tranny) tows about 2K lbs less than the Tahoe/Yukon is tire size. 35" tires on the H2 provides essentially a roughly 20% higher gear ratio than on the 30" tires that come stock on the Tahoe. Thus, the H2 can tow about 20% less. That's why those big Sierras and Silverados some with ridiculous 245s - they are rated to tow a lot more with iddy biddy Class-E tires - it helps the towing specs. If you put 30" tires on an H2 (or lower rear-end gears), you could tow 10K lbs with no problem.
