[Special T]

XL.are.a directional tire and shoild work well in softer material

Has anyone put 395s on the front while running regular a3 tires in the rear ? I prefer not to spend all the money at once

I would keep all the same size tires on the truck.

Remove the front drive-shaft. They are just enough different that it could cause some serious damage if the front is engaged. I'm going to 4x4, partially because of this cost (and I like the looks/performance).

I would take the spline caps off if you did that. No binding of the drive line for sure.

I’m adding Goodyear 395s to my A3, on A3 rims. I love the look of the stone shields. I am not running ctis and have no ctis hardware on these rims. Will adding the stone shields throw my wheels out of balance or not impact them?

 

[gimpyrobb]

I doubt there would be enough weight to throw off the balance if just using the rock guard.

You could put a couple extra nuts on the bolts (that bolt the rims together) to add small amount of weight on the opposite side. A static balance would tell you where you are to begin with.

One way to static balance is on the truck. I decide which axle set I will repack and put new seals on then remove axles, seals and completely clean the bearings and housing. Reassemble without the seals on one wheel and make the bearing to where you can just feel resistance on turning and then back off about 1/4 turn. With no grease or seal, it will turn easily. Mount the tire and wheel being balanced to that hub....the heavy spot will fall to the bottom. Then add weight to the top until you can turn that heavy spot to 90* and it no longer drops. Move that wheel/tire to one of the other axles and go to the next wheel.

Install new seals and repack grease then you are ready to go. I think front works best but any will work, the axle is just a bit harder to get back in on the rear.

I have some of the M35A3 CTIS weights for the wheels if your interested.

Since the CTIS is gone, there is too much weight in the standard weight block.

I’m looking at putting 395s on my a3. I use it for plowing and need to run chains. I don’t think I’d have room on the rears, but any thoughts on rubbing on the front with chains?

 

[tobyS]

Rears will have only 2" between them (so chains will hit) and front, I believe, will hit steering arm with A3 wheels. There may be a different wheel that could work to put the front further out (less back space).

 

[Briand]

Was afraid of that. Looks like I’m going to have to start saving my pennies for them continentals

 

[tobyS]

What Continentials and why would they work better with chains?

 

[Briand]

Continental MPT-81 365/80/20. It’s the only direct replacement I’ve found still available. The stock 14.5x20 Michelin XL tires that are on there now work fine with the chains.

 

[tobyS]

Here is another option that might work....365/85R20 Michelin XZL.

Rodney has a deal going on flee-bay @ $325 compared to $515++;

Had to remove link...I think it's against the rules to post an active one.

Enter the size on a flee bay search and Rod's place in Wisconsin comes up. They are good to deal with and have reasonable trucking costs.

 

[Briand]

Thanks for the lead, I’ll give them a call. Looks like thats going to be about 1.5” taller but the same width. I’ll have to lay a chain on the front with a full turn and see what I have for clearance I guess. I could stand to lose the rear chains, but not all of them.

 

[tobyS]

Have you thought of having one or two axles with air lock differential?

 

[Briand]

Thought about it, priced it, and added it to the list. But plowing I need the chains to bite into the ice and packed snow.

 

[tobyS]

On my list too...about #18.
