I purchased Lynx (black) with Continental HTL2 Eco Plus in 215/75R17.5. I didn't buy a spare in that size since the existing tires are very close to the same diameter. I also used the RV size Dyna Beads to balance the tires. I was the first retail customer Scott from Trailertiresandwheels.com where he used the RV size Dyna beads. He did about a month of internal company testing before using the RV size Dyna beads on my wheels. All in all a very good experience. I went with the Continentals for the improved fuel economy (i.e., low rolling resistance tread). I'm anticipating perhaps a 3% improvement. I have not had my rig out since getting the new tires and the small improvement may not be measurable. Once down side to the Continentals is that Continental will not pay for damage to a rig caused by a blowout. I checked, per Scott's advice, with my insurance company (i.e., USAA) about coverage and USAA said my comprehensive coverage would cover damage from a blowout. I do not believe all insurance companies will cover a blowout so you may want to check your insurance coverage before buying Continentals. I'm planning on running 115 psi in the tires which will handle about 4,000 pounds per tire per the load table. I don't have a current weight on my rig so I may have to adjust my pressure once I get my rig weighed. Hope this is helpful.
