Hey all,

I'm not a big fan of the absence of a spare tire in our cars. Just wondering if anyone is running with a spare? Recomendations on where to get one and what to get? Do the Chargers/300 come with a dumby tire that would fit on Cali?

Thanks,

Where do you plan on putting it?

The problem you're going to have is that the spare has to be big enough to clear the bigger brake rotors, and has to be an 18" wheel. That rules out using one from another Caliber. Being that the spare on the other Calibers is nearly all wheel and little rubber, if you found a spare wheel, I doubt you'd find a tire with small enough sidewalls to fit in the cargo area. It might be easier to just by 4 run flat tires.

The regular Caliber spare wheel well is designed for a 16" space-saver with Tire T155/90D16

Available from Chrysler or salvage. The bolt pattern is 5/114.3 4.5"

BUT SRT4s do not have spares because the minimum wheel size to clear the large front brake rotor would not fit.

Dave's right. You'd be better off carrying a tire plugging kit and small air compressor around with you that plugs into your cigarette lighter.

The flat fixer pump is both a gunk delivery thing AND a regular air pump.

No need to carry another pump just for air. Jet yourself a flat fixer thread thing for fixing a puncture if you can find it. use the flat fixer spray if you can't locate the puncture.

I notice that the rear calipers are much smaller than the front. See my pictures below, first the front wheel, then the rear. The rear has a full 2" of clearance instead of 1" for the front.

Dodge describes the SRT4 brakes like this (from http://www.allpar.com/cars/dodge/caliber-srt4.html)

"The brake system is using the 5.7L Dodge Charger police car front calipers. It is actually the export 300C 5.7L pads and the police car brake pads will go on. You can buy those from Mopar. Those are a little more track capable if your main focus with the car is at the track.
The rear brake is essentially a Sebring rear disc set up. We have pretty darn stiff calipers and I think a pretty good pedal feel. I think especially for a slider (floating calipers), this is the benchmark brake system for our segment."


So my question is, can we get a Sebring donut that fits the rear wheel? If you have a blow-out out on the front you just have to replace a rear wheel with the donut, then swap the front blow out for the good rear wheel.

From the way I read that, it seems like you should be able to do that. If there's a junk yard near you with a Seabring, why not try it out?

The Export Calibers with the 16" Spacesaver spare fit the front caliper

Brake Rotors Front 11.6" x 1" ( 294 x 26mm) Vented discs with ABS

The SRT4 rear rotor is 11.8" x 1.39" (302 x 10mm) so larger but not by much.

Could be worth trying if a Calibuddy has one.

The Sebring spare may not fit in the Cali trunk well.

I can deal with the tool kit. There is like 8 cubic feet of space under the seats...Compared to my SS Cobalt where I can't even fit my hand under the damn seat.
Don't care about the extra weight and I hate the thought of not having a spare. I guess Im going to have to get a patch kit. Already have the pump. I do like Frank N Furter's idea of doing a switch with the rear. It could get me out of a jam. Especially with winter coming up.

I'm afraid all my Calibuddies are state-side mate. Anyone know the size of a state-side Cali spare? Will that work in the rear of the SRT4?

I can't get the 15" Caliber steel wheels to fit on my SXT.

My temp spare is size T155/90D16. If i were you, i would go to a junk yard. Get a temp. spare from a Caliber and have them jack up your SRT4 (if it clears the "front" rotor and caliper, it should clear the rear) and see if a temp spare will fit. If it does you could also buy a jack and lug wrench while you were there.

Banshee, I talked to the dealer and my tire shop. Both were concerned that since the car has big 19" wheels, that if you put a donut from another car on the rear, it would have a smaller overall diameter than the other wheels and that it might "do damage" to the suspension to drive around with like that.

I am not sure if I buy this concern. Nobody else has raised that concern yet on this thread and there are some pretty sharp mechanics on this forum. I could see on the front wheels which are powered it would be different. But don't our rear wheels just kind of go along for the ride?

Any help out there?

If you use a donut as a true temporary spare, you can probably limp home or to a shop (but nowhere else). A big tire diameter difference could possibly "confuse" the ABS or Traction Control under panic conditions. But then again, you would probably be driving pretty easy on the donut.
