I just bought 5 18" wheels to replace the 15" wheels on my 05 TJ. Looking for the Spidertrax spacers I need now (I think I need to go from 5X4.5 to 5x5 and am trying to find a used set). An 18" wheel won't fit on the spare tire carrier and even if I got the spacer for it, the tire would block and be hitting the 3rd brake light. Do I even need to worry about the spare, or will my 15" spare work if I get a flat? Thanks and happy holidays!
Although my tires are not as big as yours(33 12.5 15) I just did this today. I used 4 flat washers as spacers to bring up the third taillight. That gave me about 1/8th of an inch clearance. Like BLK00tj was saying you can get some evenly cut pvc pipe and paint it and you would not even see it, only worry is that the wiring would be long enough.
The tires on the 18" rims I bought are Bridgestone Dueler A/T 255/70/18 and the tires on my current 15" rims (and spare) are 225/75/15. I measure the new tires at 32" across and the 15's at 27" across, so if I had to actually use the 15" spare, I guess that axle would be sitting at about 2.5" lower.(One of the Bridgestone tires is like new and the others are shot, so I figured I'd buy 3 new ones of the same thing.) My question is if I had to actually use the spare (on the street) would this work for a short period or would I risk serious damage? Thanks. Also, I understand how to raise middle brake light so it would clear, but how can I change the spare tire bracket to hold the new 18" wheel (5X5 bolt pattern vs current 5X4.5)?
A 32 will fit in the stock bracket. Many of us have 33's. Put an adaaptor on the brackes. The most important thing is that the snubbers on the tub and gate are tight against the snubbers. You will have to space them out to remain in contact with the tire.
