As the title suggests. What is the largest tire I can put on my stock 2018 Touring? The Duelers are shot at 60k mikes and will be replacing them asap. I would like to go wider/larger if it makes a difference and wondering how big/wide I can go without rubbing at all

Thanks in advance!

Good afternoon,

Few fitment options however you may want to measure on your vehicle from the stock tire to determine if it would interfere with anything. 245/55R18(28.6") should fit - same height but 3/4" wider. 245/60R18(29.57") would be 1" taller and 3/4" wider this may rub though. Ill send you a PM, we would love to help further.

Once you change tires from the OEM you will likely see a MPG drop already then if you go wider or taller etc that usually means a heavier tire with more rolling resistance so dont be surprised if you see a 3-4MPG drop.
