The 3055 does not have a lot of weight on the axels. The E rated tire is fine. You could step up to the G rated tire if your rims are rated for it and they should be. Crawl under and check the back of the rims for 110 PSI. If you check Goodyear's load rating chart for the G-614, you will see what they are rate for at various pressures. You don't need to run 110 lbs in them, running them at 90 will give you some additional load rating over the E tires at 80 but at a harsher ride. The best ST tire on the market is the Maxxis. Stay away rom the Goodyear Maraton.
