Hey all.

Should I go with a 4.00 or 4.50 on an 18x3.5 rim? Anyone have any pics of either setup?

4.5 will be better for that width.

Is it 3.5" measured between the inner beads..?

Is it 3.5" measured between the inner beads..?

Yes it is.

 

[Danny F.]

Yes it is.

It's more suited for a 4.50" then.. but isn't there a shop around your area who stocks both the 4.00 and the 4.50 tires..? If so,you can always ask him to trial mount them both so you can see which look you prefer..

 

[iflybyu]

THat is a good idea...I will have to call around and see.

I have a 4.00 on my front and a 4.50 on the rear. They are VERY close to being the same size.

Are they both on an 18x3.5 rim? If so, could you provide a pic?

 

[Spring-Onion]

Here is one but I am not sure what view are you looking for? I should also clarify that mine are the Coker firestone replicas. But the sizes should be close.

Spring-onion, Thanks alot for the pics.

Are they both 18x3.5 rims?

Thanks Scottto93

FWIW- I have 19" Coker ANS 4.50's mounted on 2.50 rims and they're fine.

 

[Spring-Onion]

Yes if you need other views let me know. They are damn close to the same height just the 4.00 is visually thinner.

 

[iflybyu]

Spring-Onion,

Can you get a pic of each end on so that i can see how thin the difference is?

Mike

 

[Spring-Onion]

It's hard to move around all the shit. If you want more I will drag it out in the light tomorrow.

Keep in mind that most 4.00 & 4.50 x 18" classic style tires on this board are mounted on the early OEM style 18" x 2.15" wide rims..

Your rim is 18" x 3.50" wide.. so you can't really compare what your end result will be before you trial-mount a 4.00 and a 4.50..

Not that the difference will be fenomenal, but it all depends to what look you're after of course..safetywise you shouldn't have any probs..

(Hell, I've mounted 5.00 x 16" Firestone's on 5.5" wide rims.. )

Keep in mind that "stretching" a tire designed for a 2,15 rim on a 3,50 rim will actually reduce the tire diameter, so you're probably better off with th 4,50 18 tire.

 

[iflybyu]

thanks for the pics and all the info, i really appreciate it.

This is from some searching I did on the issue a few months back
Not sure if it adds anything to your decision but figured I'd drop it here

Quote:

Rim Width Range Because tires have flexible sidewalls, a single tire size will fit on a variety of rim widths. A tire's rim width range identifies the narrowest to the widest rim widths that the tire is designed to fit. The width of the rim will influence the width of the tire. A tire mounted on a narrow rim would be "narrower" than if the same size tire was mounted on a wide rim. NOTE: Because the overall diameter of a steel belted radial is determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width. The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10".
