I would like to put 31X10.50 r15 on my 87 F150 4X4 will they fit with no rubbing or do I need a lift kit???? What is the largest tire that will fit 15" rims without a lift kit????

 

46" IROKs



find the search button, click, type "biggest tire on my truck", click 'search'....wait patiently....read old posts of the same question asked a million times untill you find your answer.

I have a 90 f150 4x4 with 31x10.5 on 10" wide rims, they clear nicely.....I have a 1990 bronco that has 235/75s that barely clear.
Just search, use your best judgement on whether or not your trucks suspension is old and sagged or not. If its sagging, you wont be able to run as big of tire as you found out earlier, while using search

 

I've ran 31's in all widths and I've had 32 in on one of my trucks lighty rubbed . Had a 89 bought new . 302 5spd quad shock . Dealer had install 31x11 on stock spoke rims . As well as larger gas tank and tarp. And running boards No problems with rubbing. I like pud says depends on condition of truck. Are coils original, did truck haul alot ect. Take the easy way. Talk to somebody you know that has size. TAke an hour and swap rims and tires to your truck . Take small drive and steer lock to lock . And see if rub . good luck.
