CruisinFJ60's 82 BJ42

[CruisinFJ60]

ordered a heated grooving / siping iron to to the 38.5's on my 60 and and to sipe the tires on the 42, i know some of yall have done it with a razor blade and some soapy water and all i have to tell you is... your retarded... spend the 60 bux and save yourself 4 or more hours!!

The Iron makes 2 slices for each time you go across the tread bock and most of the tread blocks have 8 cuts / sipes in them. I only did the center blocks and mostly for improved wet traction as we dont really get ice or snow down here. the siping also is said to reduce the heat in the tread blocks and will prolong tire life from the reduced heat so that is another plus.

then after i finished i turned the blade around to do some grooving, I decided that since i do wheel the 42 a little a little extra traction wouldnt hurt when off road. so i decided to groove the outter lugs a couple of 32nds to help give it a little extra bite.

I followed the curve of the tread block to keep it structurally as strong as possible and to reduce the possibility of chunking if i were to get on some rocks and were spining the tires for whatever reason.

anyhow here are some pictures.

1.) this is a BFG MT KM 33x10.50-15 as you can see i sipped the center lugs then groved the outters
2.) pile of rubber from grooving 2 tires.

1.) one of the other ones i did, it is obviously grooved and sipped as well but it is easier to see on this one.
2.) and the final pile of rubber from all 4 tires.

I should mention that sipping doesnt remove and rubber it just puts little cuts into it, the grooving is hat removes the rubber.

To sipe 2 tires (did the other 2 the night before) and to groove all 4 of them it took me about 2.5-5 hours, but that includes letting the iron warm up, moving truck to driveway, unbolting a wheel, doing it, bolting it back on. moving jack, unbolting next tire, doing it ect.

Any comparisons on how the tires are on-road and off-road before and after the siping and grooving? I have been thinking about doing this to mine and was curious to hear your review of this.

no not really, i didnt have any issues with spinning in the rain before and i dont now either. they are not any louder than they were before.

what i can say was down at round up i was in some mud and didnt have any issues and the stuff was really pretty slick 2wd and 1st and second gear didnt spin unless i made them spin and im open still. it took me a little bit but i think it made a pretty decent amount of change just from that little bit. i havent wheeled it since i did it but if the signs of improvement are any indication of what to look forward to it was totally 100% worth the time to do it.

not to mention i think they look cool.

yea i didnt really expect it to get out either, i felt it move then stop then randomly started going again. and it didnt even really dig in all that much and i was just off idle too.

Well I no longer own the BJ42 but now I have a cool FJ60 Truggy that has been bobbed 16 inches... Hope you enjoy it Joel.
