'85 C10 Recommend tire size, stock height and rim, LS swap
« on: September 14, 2018, 08:12:05 AM »
I have a 1985 C10, 8' bed.  Stock height, stock 8" rally wheels.  I like the stock rims and height.  2WD.

I have an LS6 cammed LQ4 6.0 dropped in it, and regeared with 3.73.

I am looking for a recommendation for optional tire size.  My goal of my vehicle is to be a truck that is a sleeper, not a drag car that looks like a truck.... if that makes any sense. 

Thank you!

255 70R15 is slightly taller that stock, fit the 8" rims well.  To me the perfect tire size for stock rims riding at stock height

Thank you for the input zieg85.  Greatly appreciated. That is right in the middle of what I have been kicking around.

My truck currently has 275/60R15 BFGs in the rear, and 255/60R15 BFGs in the front.  I cannot stand the smaller tires up front... but that was what was on the truck when I bought it.  There is plenty of clearance for the 275/R15s in the rear, I'm relatively content that I can put the same up front... but I would like to try a little taller, or am I pushing it? 

I have a set of 235/75R15 Michelin Defender LXT tires that I kept off of my 1990 F150, with only 15K miles on them (80K tires).  I would be interesting in using these, but would like something wider.

235's look fine and Michelin tends to be wider than most.  Here is 235's on the same truck but with 7" rims

Excellent, I will go that route.  I still tuning the LS, the taller tires will work in my favor. 

This is how mine sits now... hate the smaller tires up front!

I never do 60's on front but I see what you mean about tire height.  Mine was a 84 4.1L 3 on the tree with a 2.73 out back.  You couldn't be in a hurry to do anything but once it was wound out, it cruised 75 perfectly and got 17 mpg with a topper on it

235/75R15 Michelin Defender LXT tires all around

Much better.  Looks like a truck again.
