hey guys just wondering who is running 225s? everyone seems to run 215s as the non standard tire on their jimny. now i would love to have 235s but don't want to have to deal with having to get reduction gears.. looking at pics of the 215s they don't look that much bigger? and i cant find pics of anyone running 225s and weather they think they are better than the 215s? you'll have to forgive my noobness to the 4x4 world. I've gone from a wrx as a daily to a jimny. cheers. |

235s on a late model jimny r ok, if you go rock crawling or doing steep climbs u will have to slip the clutch, but for on road or sand i dont see the problem, im running 31s on standard gearing and only ever have to worrie on really rocky sections |

assuming you mean 215/75/15 versus 225/80/15 versus 235/75/15, 225/80s and 235/75s are basically the same, height wise, but the 235/75s are slightly wider. i run 225/80/15s but on a vitara, i dont think gearing will be to much of an issue but i dont no about clearance. |

if you're doing any kind of rock work you're going to want reduction gearing with anything above a 215.. sure theres people here who say otherwise, but theyre all people who've not addressed the gearing on theirs and dont know any better =) i'd have a good, long hard think about what you're gonna drive in it first and then mod accordingly. IMO a jimny on 215's with 2" lift and airlockers is a pretty sweet little package. Sure, its not hardcore or extreme or whatever, but once you learnt to drive it you'd easily be keeping up with all the bigger rigs on the tracks. |

and again you have a 1.6 engine!!! 
remember some ppl, specially new member dnt know bout your rig, so try to specify that before give a wrong comment, or better say not "wrong" but they would get the wrong idea 
a standard 1.3 jimny would never be able to move 31s that easy as you make it look in your comment

yeah i have heard mixed reactions as what to run. some say 235s will be fine some dont. im going to upgrade the clutch to a HD one soon anyway i think. the only reason i was asking about the 225s over the 215s is because i get stuck on my diffs pretty easily in ruts. rather annoying. |

being stuck on the diffs just means taking a different line to start with - you'll learn the position and clearance of your diffs with practice, and find you'll be able to drive things far easier than you used to. one other thing, is that getting stuck on the diffs is subjective, sometimes the diff might be touching but the lack of traction is what is not pulling you through - this is sometimes where a locker will help. where abouts are you doing all your driving that you're getting hung up on diffs? maybe we can organise a trip and have a spotter or two guide you through some bits you're getting stuck on and show you that you can drive them? =) (ie: excuse to go 4wding). |

If you're thinking 225/80 instead of 235/75 because the 235 is taller you'd better re-think it as the 225 is actually slightly taller by my calculations; 225/80 - 225mm x 80% = 180mm 235/75 - 235mm x 75% = 176.25mm Feel free to correct me if I'm wrong guys. If your new to 4WDing and you want bigger tyres there's a very good chance you'll fry your clutch pretty quick on the more technical driving. However, if you have good 4WD technique you'll be fine. I drove on 235s for a long time without gear reduction but always new it would be of benefit. Now that I've experienced lower gears I can't go back. I've never had a HD clutch so can't comment apart from what I've heard. Cables are an issue and I think that the main difference is the stronger clamping pressure which in my mind is of no benefit if you are slipping the clutch anyway. Paul |

your right i do have a 1.6, but i was but i was reffering some 1 to a vvt jimny, there is a guy in perth with a vvt 1.3 running 31s and drives his pretty muh every where, I do know wat its like to drive with reduction gears, just at the moment theres no need, i spend more time on road and in the sand then any where else, there on the to do list tho |

true well the last time we went out it was muddy as. i didnt have alot of grip and yeah ended up being beached on my own two diffs. i dont think ill be hitting much other than mud and sand, with the occasional visit to the power lines. i think ill look into those lockers as well, can you recommend any? other than that i think im sorted. thanks guys for your help. |

Tall tyres and a locker with standard gearing is a terrible combination. The added traction of the locker amplifies the gearing problem because you can't keep the engine ticking over through wheelspin. Slipping the clutch to overcome a lack of gearing is totally 1993. Steve. |

Steve. my post implying lockers would help was after my post saying to address gearing =) i was just saying that if he stuck with smaller tyres to avoid changing gearing and got a locker he'd probably be more capable than bigger tyres and no gears. (ie: spend the tyre money on an airlocker). |
