I'm an old guy who just bought a 2002 trek fuel 80 full suspension bike in like new condition. Needed tires, I had no idea the recent bike tire choices were so complicated! Google AI guided me to different tire choices, based on my intended usage. ( fitness riding, mostly paved trails, possibly wet conditions, some gravel or off road use.) 1.75" semi slick on rear, 1.95" kenda bite on front. Safety, efficiency and ride quality were considered in that order. I put 160+ miles on the new tires so far. Been changing tire pressures, noting changes in ride. These tires, and the bike hit a nice sweet spot for my usage, between super wide mtn bike tires, and narrow road bike tires. Very happy with the results, posting 20 mile fitness rides in the 10-12mph ave spd range. Not jumping off 10 foot jumps, but i can launch off a concrete curb no problem. You guys seemed to have the best price and super fast delivery. Good job. Thanks!
