5"/6" lowered, Tyre size ?
I have fitted a static 5"/ 6" lowering kit to my 77 C15 and Im now have clearance issues on the front with the 275/60/15 tyres fitted at the moment. What size tyres are you guys using with this much lowering ?

I run a 235/70 15 on a 7 inch rim and a 255/70 15 on a 8 inch rally and no troubles. I wish they made a 245 thou, the back is a little tall

This is the mathematical calculation but sizes can/do vary per manufacturer. That being said, blazer2007's combo doesn't help unless the clearance issue is caused by width/back spacing vs. height: 235/70-15 = 27.95" for his front tires. To recommend a solution, more info is required. Where is the 'clearance issue'? |
Re: 5"/6" lowered, Tyre size ,
Its rubbing the inner wheel tub and catching the wheel arch.
Been looking at 235/60/15, 26.10" high and 9.30 wide or 225/60/15 25.60 high and 8.90 wide but would like to know what you guys recommend ? |

There's always the aftermarket inner wheel tubs to (like Slosh Tubz). |

8 in. rims are too wide, I could,t make them work up fr. went to a 7 in.

Back spacing, diameter, & overall OD of the tire all play a role. An 8" wheel can fit w/no issues @ 5" of front drop & stock inner wheel wells...

It's a 245/45-18 @ 26.75" OD on an 18x8" wheel w/5.25" of back spacing. A 245/60-15 @ 26.57" on your listed 8" wheel size would be another option that's slightly shorter than the 255/60-15 I recommended above. Also..... How is it lowered? Soft spring rates can contribute to buzzing on the tops of the inner wheel wells. Back-spacing can have an impact as well. Your 8" Truck Ralleys should work but you need the right height of tire & the right spring rate/shock combo to live a quiet life. |
Re: 5"/6" lowered, Tyre size ?
He mentioned it was a 15 x8 inch rally is what I was talking about. The 235/70 offers a taller tire for clearance on a static drop but clears the inner wheel wells on a 7 inch rim. I,ve tried a 60,s profile but with crappy roads and summer construction it is to low on the A-arm . Embarrassing when you have to use a 2x4 to get over a cut out asphalt.

I have 3" drop springs and 3" drop spindles up front on my 86 C10. I am running 8" rallies with 255/60 up front and 275/60 in rear, no rubbing anywhere. Your truck looks so clean man!

I tried no bump-stops (crazy bad w/o anything) & then trimmed-stops (much better but would still buzz more than I liked) so I went back to unmodified stops. Mine only buzzed @ the top of the inner well so I knew I needed to limit travel if I wanted to run a decent height tire. Some guys will opt for a shorter tire but I don't like the way it looks (well... I can't stand it is more appropriate). The ride was rougher because it was on the stops more but I preferred that over the buzzing/contact @ the wheel-well. If I do one now for someone, I'll explain my past experience & highly recommend purchasing an aftermarket/new replacement spring w/a KNOWN spring-rate. A "drop spring" isn't good enough. You need to know the spring-rate. If you utilize a higher rate spring that has the desired 1" drop along w/a properly valved shock, you're much more likely to have a better drive quality & it will help keep it off the bump-stops. Modified (taller) inner fender-wells are worth considering as well. My trucks were budget builds so I went w/the combos I did because of my budget @ that point in time. These days, I wait & get the right spring for the best ride @ the new lowered ride height. |

Ordered some 255/60/15 tyres today then fitted the new bump stops but I don't think they will work :(

I had a full coil removed off of my >100k HD small block springs in my 74swb pictured above which is >/= 2" coil drop & still had about 3/8" gap between the bump-stop & the bottom of the x-member. It wasn't much, but there was a gap. Bump=stop contact while sitting still = full time rough ride. |

255/60/15 front tyres and it looks like its not catching anymore I also swapped the -1" springs for -2" springs because the ride was the same on both but the -2" springs were stiffer plus I have made up some bump stops giving me some movement now.
Next up I need to lower the rear a bit (hard to see in this picture but there's a good rake) to level it out so I have some 1"/2" drop shackles on there way. |

Scoti, what's the difference between the HD small block spring and the 454 spring?
