With a 3.5" front drop, will a 255/50/20 tire fit? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

UATahoe · 03-06-2018, 02:50 PM

This will be on an 87 with an LS swap. I will be running a 2.5" drop spindle and a 1" lowering spring from ridetech. Rims are the Ridler 695. 20x8.5 with 4.75" backspacing. The tire works out mathematically as a 30" tall tire but i am guessing it will come in just under that as most tires seem to run under their measurements.

I am hoping they will fit but wanted to see if anybody was running something similar and could give some feedback. Thanks!

I used to have that tire size on the front of mine with djm drop spindles. I just dont remember the offset. I have 5” offset 22x9 now and run a 265/35r22. One thing you have to be careful of is whether the center cap will fit over the dust cover on the spindle. I hope this helps somewhat. I haven’t ever ran Ridler wheels, but I would definitely call them up and see if they can give you any input on the fitmet.

I have same spindle and spring and same wheel as you and have 275/45/20 on mine does fine only had a slight rub when I was running about 75 and hit a dip in the road and it was on driver side only haven't had any issues other then that one time and it was just a little scuff hope this helps

Awesome! Thanks for the feedback guys. Rickit, any pictures of your setup you could share? Would be awesome to see the stance.

Perfect man. Great looking truck. That stance is exactly what i am shooting for . Agree with pulling up the rear bit. I like a little bit of rake on these trucks. What are the drop specs on the rear?

rickit · 03-06-2018, 05:14 PM

rear axle is flipped

UATahoe · 03-06-2018, 05:17 PM

Gotcha. So roughly 5". Mine is lowered 4" in the rear with lowering leaf springs from western chassis. I have some drop shackles in case i want to go lower. I do feel like my truck is sitting higher than most though. At a 4" drop, it just doesnt look very low at all. But it may need some time to settle. Its been sitting without the bed on for almost a year. Finally got the bed on last weekend.

rickit · 03-06-2018, 05:27 PM

my overload springs was remove mabe why my seem to set lower i like a little rake myself

UATahoe · 03-06-2018, 05:35 PM

That would make sense. Yep, i like a little bit of rake as well. Little more of an aggressive stance. Judging by that i am thinking i might end up needing another 1" lower in the rear but i will let it settle for a bit and see how it looks.

Thanks again man for all of the info!
