Toyota FJ Cruiser Forum

Two-Part Question:

Would bigger/wider tires increase the stability of my Cruiser .. ? I think I would feel safer with bigger/wider tires especially while speeding and taking turns (then again i could just slow down- hahaha)

If so, what is the biggest set of tires I can get?

Bigger, as far as taller will make it more unstable. Wider or putting wheel spacers will make it more stable. putting on any tire that will have a larger contact patch will hurt your fuel economy. Hope this helps.

i just swapped back to my stock tires from procomp 305-65's mt's got a whopping 3 miles per gallon back as well. i will put them back when it gets cooler here and we start going out more again.

After driving a Jeep Cherokee for 4 years and having owned a Wrangler, I can tell you honestly that the FJ is MUCH more stable on and off road than a Jeep. I find myself taking off-ramps 10-15MPHs faster than I ever could in my Cherokee, while feeling perfectly safe. The only problem is I tend to stare at my Clinometer to see what kind of angle I am pulling around the corner...thus I take my eyes off the road My advice is to leave your tires alone. Adding un-sprung weight(wheels and tires) greatly reduces your gas mileage, and I always say just leave well enough alone.

personally I'm not to concerned about the fuel mileage as this machine doesn't get that good of milage anyway, I did the change for the looks. i have put on pro comp 33x12.50x17 mud terrains on the stock wheels with a 3" lift. i did notice a bit of a power loss so to compensate i installed a magnaflow high perfomance cat back stainless exhaust. i now have more power and get better milage than this machine has ever got. as far as stability goes I don't think there is a more stabile 4x4 out there with functionality and incredible looks of the fj cruiser
