Question About 285 BFGs

[Stepside Z]

I know alot of guys have replaced the Firestones on there Silverados and Serrias with 285 BFGs. My question is has anybody replaced the spare and does it fit in the spare tire holder?

[RyanbabZ71]

I changed the spare out to a 285.  It fits underneath Fine.  No clearance problems at all.  I also have the towing pkg and it doesnt interfer.

The 285 does weigh more.  I recently took the spare off and i gained a little height in the back.  I am thinking of chaining the tire in the bed.  

But dont worry the 285 will fit underneath the truck

Makes alot of difference going from those P-rated factory tires to a LT-rated load range D tire doesn't it?   LOL

Thanks. I forgot to mention that I had the tow package. When I change the tires I am going to change all 5. I am also planning on changing the shocks to Bilstein HDs.

do the bfg 285's rub at all or do you need to adjust the torsion bars ?

[RyanbabZ71]

the 285s do not rub on my truck.  Didnt have to mess with the torsion bars either

For my '98 I did have to adjust the torsion bars.  Don't know if there is a difference in the well size in the old body style vs new body style.  I also keep the spare in the bed instead of the holder, so I'm not sure if a 285 would fit in it for the older body style, haven't tried....

Next question that came to mind. If I put a Flowmaster on and ran duels out the back how would that work with 285s?

Run the pipes on the outside of your reese hitch. You might have to tweak them if you buy a kit, but they will probably fit.

Thanks for the info. I want a little more tone from the truck but want 285s also. When I make the change to BFGs I am going to change all 5 tires. It will be a while befor I make the change so I want to make sure I do the right thing.

The 285's will make a difference.  Yesterday i parked in front of a reg cab Z71 with 265's.  You could tell from a distance and up close my truck sat higher up.

i put BFG 285's on my truck after seeing ryanbabz71's truck. I didn't have to adjust the torsion bars at all. I saw on another forum that sometimes this causes ABS problems. What exactly does it cause and how do you fix it?

[RyanbabZ71]

Braking problems:

On my truck it seemed to take longer to stop.  I bought an HPIII programmer and set it for 32.75" tires and the brakes seem fine and have for about 7K miles.

There shouldnt be any safety (braking) concerns.  

The abs on mine doesnt kick in (not sensitive like it was)

as much as before

I didn't have any trouble fitting the 285s on my truck.  I am even going to step up to the 295s when these wear out in another 35,000 miles.

As far as a Flowmaster exhaust and your spare, don't worry.  I have a flowmaster system and the pipes aren't anywhere near interfering with the spare.

I do know that I will have to take the truck to the dealer to have the ABS recalibrated. As far as the speedo goes I checked and it will be approximately 2.5 mph off @ 65.
