Hi,

Could I pleae have some info on tires. I have a
2000 F350 V10 lariet LE 4x4 dually with a 4.30 rear end.
I bought this truck based on the information I read in previous posts.

Great Truck!!!!! thanks for the help and wisdom.

The tires have 20 K and I have to start looking at new ones. Maybe 20% tread left on them. I read in previous posts that increasing the size of the tires will increase gas milage. I know it will also decrease towing capacity but I am not too worried about that. What size can I go up to? Is it worth it?
I will be doing alot of traveling in this truck. 1000-1550 miles at a shot. Sometimes towing a camper most times not. Any recommendations?

Part two. I looked at the sticker in the door jam and it did not have anything under the axial section. The metal tag attached to a bolt on the differential had 43-10 on the top line and 4.30 under it as I stated in my previous post. I am assuming I have a regular 4.30 rear end. Any other things to check like the VIN? What diget would I check? I would think this truck would have a LS diferential.

The first thirteen letters of the VIN are
1FTWW3359YEE3.... What do I have?

I didn't get a owner manuel or any records.
Thanks for your help





Any recommedations?

Man, a dually, you got me! You have to worry about those two tires out back rubbin' together.

>>Is it worth it?

Depends. What are you trying to accomplish? Better mileage? I'd say yes to that. But you'll lower it's towing PERFORMANCE! A strange thing to do on a F350 Dually. If the tires have the same weight rating as the previous tires you capacity shouldn't go down (that much anyway...)

>The first thirteen letters of the VIN are

1FT = Ford, USA completed vehicle
W = 10,001-14,000 GVWR with Driver & Passenger second Gen. air bags
W33 = F350 Crew Cab Dually 4x4
5 = You got me! It should be the engine code Your V10 = S
9 = Check digit (not you, that's what it's called)
Y = model year 2000
E = Made in Kentucky
Last 5 numbers are the vehicle build sequence #.

 

As monsta showed in the VIN breakdown , there is nothing there to indicate gear ratios. Based on the info you posted, I'm pretty sure that you do not have a factory limited-slip differential. Many people don't think they are worth the extra $$ so it's not unreasonable that your truck would be without it.

About the only chance you have of increasing MPG with tires is to get taller and skinnier ones then keep them near max air pressure. I don't know what size you have on the truck now, but 235/85R16E is a factory size that is available.

 

 

You can check to see if you got a LS unit when you get your new tires. With both sets of rear wheels off the ground, you or the tech can spin one side. If the other side turns OPPOSITE then you have an open diff. If it spins the SAME way you got a LS.

 

Thanks for the info. :-)

This is a great site with alot of good tech stuff as well as some fun
debate.

I love the truck. The first thing every one says when they see it is " Thats a big truck" The second is always "how much did it cost"

I never answer and let them wonder. Anyway Thanks
