Tire question

another question for you guys... i keep seeing these lists of how much lift you need to fit whatever size tire and i see that for the 32x11.5 tires i've got now under my 1990 k5 4x4 i should have a 2" lift... what's the deal? my tires fit fine, tons of clearance. i'm thinking of getting some 33x12.5 tires without lifting my truck. anybody else noticed this or know the reason that they say you should lift the truck so much to fit these tires? i mean i understand the whole clearance issue but like i said according to the listings i've seen i should have a 2" lift but i don't see the need cuz they have sooooo much room, hence my decision to get a bigger tire when the ones i have are done. i just dont understand why it says i should get such a lift...

Re: Tire question

i dont think thows charts are that acuret, one sead i needed 6 in. to fit 35s so i got a 6 in. and 36s and have a wole lot of room, ill defenitly go biger when i need new tiers, pat of it may be the amount of back spacing ther useing for wheals and mabey the with of tiers ther useing, the one i looked at dident list eather of thows

id say go as big as you want and then trim acordingley if nesasarey, i dident want to trim my fenders at first but once i started with my 33s on stock springs i just wanted to keep cuting

Re: Tire question

You probably know this already, but I think they're referring to the suspension when it compresses, and when the front wheels are turned. Just sitting, there could be seemingly plenty of room for the tires, but compress the suspension, and they could scrape, as they did on my 78 GMC. The rears usually arent as much of a problem.

Re: Tire question

Actually The charts are right. you would need 2" of lift to clear a 33" tire all threw a the range of your springs. However that is a 33" inch tire as in actual true diameter. I bet ya $20 your 32.5 don't measure 32.5 more like 30.5 - 31. infact most companies will tell you you need a 4" lift to clear a true 33" which most 35" tires are.
