Hello
First question in a long time.
And issues with the Method 305HDs (18x9, 18mm offset, 5.75 backspacing) and 37x12.5/18s fitting a 06 F350 SRW with 4.5 inches of lift?
Thanks

 

I have 4.5" Rough Country lift on my 2005 F250 with 37s on 17s....no issues at all.....

 

Thanks
No issues with the 17s. New to the SDs. I have no preference between 17s and 18s other than price Just seen where it's mentioned that some 17s don't clear the brakes.

How are the 4:10 with the 37s? Thats after the tires, and the calculators show 4:10 should put me where I want to be RPM wise at 75-80 out here.

 

nope, no issues....I'm not sure exactly what the backspacing is, i bought the rims used off of Craigslist....I think they are 17x9, maybe 10s....I have a Hypertech programer installed on the high octane setting. I think it does really good with this setting. Most people on here use the SCT programmers. The SCT doesn't correct the speedometer, the Hypertech one does. I was planning on changing the gears from 4.10s to 4.56s or 4.88s, maybe 5.13s, but I was quoted around 5k from 2 different shops here in Phx.....ill hold off for now on that. Im happy with the Hypertech programmer on the high octane setting. Mine is a V10 and I dont do any serious towing tho. damn, ive pulled the rims off many times and ive looked at the size, now i dont remember....

 

Mine will have to be able to tow, but not do a lot of it. It's a diesel and I'm looking to be around 2000rpm at 75mph or a tad higher and I'm fine cruising at 80. The 4.30 is right in there also. Right now, even kicked around trying to find a take-out rear with the right ratio and the just swapping the front R&P.

 

If you are going to be towing alot, I hve read that many guys dont want to use 37s cuz it makes it harder to handle with the larger tires towing a 5th wheel. I dont have any experience with that, so I dont know....with a diesel, you dont know need to be concerned with changing gears cuz of the low end torque that diesels have already....

 

So, this truck came with 38s and an 8" lift. I think I can drop it to 4.5 pretty easy with 37s. With the HD rims and load range E tires I should be fine. Wont tow often or heavy, just needs to be able to if the wife has the dually for some reason. This one also has a 12v Cummins in it, 1900 RPMs is my sweet spot, need to be there or a bit above to keep it from lugging.
