I’ve decided and purchased 22.5 conversion for my c4500 2wd and I plan to install them as soon as I can have a break from work. 8x275mm lug 22.5 Alcoa’s on dynatrac 255/70r22.5 ma400 mixed tires.

hate to be a buzz kill but I think those are too wide for a 2wd. Mine are 7.5" and they rubbed the tierods. I had to shave the lip of rim.

Wheels and tires fit perfect with no rub and bags dumped. Will get daytime pics tomorrow. Also center caps will be installed tomorrow if I have a chance.

AWESOME!!! It looks the way it should have come from the factory without the training wheel 19.5s. Glad it worked out for you.

Are the centre caps the old monroe ones? Or is there somewhere you can buy new ones today?

I’m not sure I still have the old Monroe ones but there a classic style and the new ones are actually a better design

Well I was worried about rubbing on certain spots and didn’t notice I had some minor rubbing on the air bag mount and had to remove rear wheels to shave about 1/2 inch to clear rear tire. Tire was shaved on lettering but no actual tire damage.

Ageed. A little flex or weight may cause a REAL bad stituation. I would do as others have done with air bags( I dont have them) I would moved the bags inward some. There is a post here that someone did.

DOT may have an issue with it also if they ever do an Inspection.

I was thinking of going with the same tires and size. How do you like them so far. More importantly, I want to know how much of an RPM drop at the same speeds before the new Stires and after, you got going with these tires that measure roughly - 37". I have a 4x4 with 5:13s and an trying to decide what tire size to go with (it'll fit 40") to reduce my engine rpm at highway speeds. With the small stock 33" tires I'm running at 2400 rpm at 65-70 mph @7.5-8 mpg and around 2100 rpm at 55-60 @9-9.5 mpg.

So far I cannot complain. Looks great to see a wheel well filled up and not much has changed with ride quality. I do recommend this setup especially if you have a 5 speed transmission like I do. I tested my 70 mph with a speed app and cluster 70 is 78 on the speed app. It did drop my rpm on longe range. Truck looks as it should have came from factory. Truck is a daily workhorse.
