Heavy Duty tires & brakes vs "normal"

[JimC]

I have a T337E and it came with 18.00x5.5 "heavy duty" tires, wheels & brakes. There's no field approval needed with going to a 6.00x6; they're listed in my POH and in the parts manual as standard. 18.00x5.5 is listed as optional.

The main issue is that the HD wheels & brakes go with the oddball wheel size, so I have to replace much more than just the wheels & tires. I can't imagine I'll need HD brakes on backcountry strips. The weakest brakes will be able to lock the tires any time on grass & gravel. I imagine I'll save about 5-7 lbs/side.

The sticker price on the full 6.00x6 kit is about $2500/side; it'll obviously be cheaper if I scrounge & scrape the boneyards. I just need to make sure I get all the parts - almost everything that goes on or near the axle is different for the two sizes.

Yep, you are good to go with the original size of 6.00 x 6. Someone must have put the newer style on at some point for the HD brakes or it was a factory option. I would have to think there are some used or surplus parts out there that should save you some money
