I love almost everything about this build but have always hated features that, for the sake of looks, take away from performance and safety, especially if I also don't personally think they look good. I prefer features that look like crap but that provide gains in performance and functionality.
Major stretching of tires to fit on ultra-wide wheels has got to be one of the worst things anyone can do to their vehicle. Not only do stretched tires perform and ride poorly but they also, IMO, don't look very good. To make matters worse (probably the main reason I don't like them) stretched tires are dangerous.
A guy at my previous work had modded Honda Civic and installed ultra-wide rims. Instead of buying appropriate tires, he stretched the tires to fit. He thought those stretched tires were ultra-cool and kept boasting about haw much stretch his rear tires had. He had gone to several tire dealerships before finally finding one willing to install the tires on the ultra-wide wheels. I rode in his car with the stretched tires and the car wouldn't go straight (kept wandering left then right) and every little bump was a loud bang. About a month after installing the wheels, while cruising on the highway at 75 mph, a rear tire suddenly deflated and came off the rim. He lost control, spun the car, and bounced off the highway barriers. Every single fender, bumper and door was damaged and his insurance wrote the car off.
I don't really know how far these tires have been pushed (stretched), but I'd be either finding some wider tires to fit those rims or I'd get rims that fit the tires.
