spare tyre

Post by jacka »

Any idea how to mount a 32" tyre on the rear of a Sierra? What mods need to take place?

Spare tyre carrier

Post by Impulsive »

Hi Jacka,

Even if you could fit it on the standard tyre carrier, something that heavy can tear your tailgate to shreds. It happened to a mate of mine with a tyre less than the size of a 31in when he took a few sudden drops while offroading.

Your best bet is a heavy rear bar with a swing-away tyre carrier, so the weight of the tyre is on the swing-away mechanism, not on the tailgate. The tailgate tyre carrier is removed totally.

I have one in the for sale section, which I'll try and shoot a pic or two of for you today to give you an idea what you're after.

Are you in a hard top or soft top ??
I ran around with a 32 inch Bfg on a 15x8 for about 3 or 4 years with some heavy off pavemet driving (Not offroading .. that's naughty :D )
The 15x8 was a 3.5 inch offset (4.5 inches outside the centreline of the rim) It would rub a bit on the rear bar .. other than that .. no mods to speak of .. (this was on a hard top)

I would go for a chassis\bumper mounted tyre carrier in that case .. the hinges on the tailgate are not all that great and both are below the centreline of the tyre (are also smaller than the hinges on a hardtop)

Could you mount it to the interior floor in the back of the car? There are some shots somewhere of NAM's sierra with a 34" Jungle Trekker sitting in the back of it - so it must be possible to fit a 32 in there... :cool:

I guess it will just depend on what else you have stored in the back there.

Note: doing this would also be good for weight distribution as you would have the tyre lower, and closer to being infront of the rear axel :cool:

Pics as promised

Hi again Jacka,
Here's those pics as promised.

The swing-away part is secured to the rear bar by a simple wingbolt arrangement, then the carrier can swing away. After that, you're able to use the tailgate like normal.

As you can see, and in terms of your PM question, the Hayman Reese towbar is integral to the whole thing, and the spare tyre carrier is very heavy capacity, and is completely independent of the tailgate (which is made of aluminium cans in comparison).

also if you have fab skills you could make a rack that goes horizontally across the tub area. the spare can be mounted on there. you still retain floor space for equipment and should should still have decent rear vision.

alternatively, you could make something like the attached pic. this is designed to sit behind the drivers seat on the inside of the vehicle. the bracket would mount to the top edge of the tub and to the floor. the floor mount could probably use the existing hole for the rear seat. the spare would mount standing up behind the drivers seat to the 3 bolts. drivers vision is not impeded and floor space is still plentiful.

Towbar

Post by Impulsive »

Dunno who made it, but it's super convenient, and all works really well.

It's bolted rather securely to the chassis, and welded together really well, so I couldn't see it being illegal. The only thing that *may* be arguable, is the ends not having the rubber caps on it still, but that's just a matter of screwing either N/T or W/T ends on it, depending on which of the two you drive.

I'm wrecking the whole car out anyway (as I couldn't be bothered installing a high steer setup on it to counteract the bump steer), so it doesn't matter to me. At the moment, it's lifted about 9 inches (in total), plus whatever the 33's give you on top of that and still registered (but not engineered...eeeek!)

Lemme know if you wanna have a look at it to get ideas. I'll be in Melbourne for a few days as of tomorrow morning, but I'll try and visit here from internet cafe's while I'm down there.

I made it.




It is legal as far as I know, can't see why it wouldn't be.

P.S.

The bushes on the swing arm are made from semi-trailer anchor pin bushes. so if they wear out, just get some from a truck spares shop.

Oh yeah, as someone mentioned earlier in the post about the weight on the standard carrier, I broke the back door in half when I had a 33 mounted on it - hence the rear tyre carrier being so heavy duty.

The more generously proportioned carry their spare in the front. I'm pretty sure its legal.
