will 31's cause vibes? - Ford Explorer Ranger Enthusiasts "Serious Explorations"®

because they are not factory specs will they cause any vibes at high speeds? like the famous 60 mph shake? i just posted in another thread how my mechanic said the cause for the shakes was bad tires. they are cupped and wearing uneven. anyway, i was planning on getting new tires, 31's rather than the 235/75/15 factory specs that are on there. i heard 31's may affect the speedo a little(i don't care) but i don't wan't them to cause any shakes or anything cuz they are bigger. any thoughts?

If you have proper alignment, balancing, and shocks, then larger tires will be fine.

i have always balanced and rotated the tires, i think they wee just no names that sucked. it has been aligned twice in 4 mos so it waasn't that. and i have replaced my shocks twice in 6 mos. i now have edelbrocks which i like, and they replaced the kyb's i had b/c i didn't like ride. too rough. i keep up on the maintenance so it was the tires that were bad. they wore from 95% new in one year to cupped and uneven.

i'm putting 31x10.5x15's on my xplorer with wild country mt's. they are real loud at about 40...didnt try at 60 but the noise is pretty cool i think...i put the owners truck on jack stands and drove around alittle with the x. good luck
