Hi, I have a set of Maxxtrac Manta 16s, they are ET10 offset, and ran with 265/75's, I think they were pretty much spot on. see photo. I might actually be thinking about moving them on. as they are now spares. Sold Def 90 HT 2010...Stornaway..(SOLD in Oct 2014)

Do you want new wheels? If not, your simplest and cheapest option is to fit a set of 30mm wheel spacers to your existing alloys, which is what a lot of people do (myself included). 2005 Td5 | 90 Station Wagon | Tonga Green

HI all
Don't really need new wheels as the ones I have are perfectly suitable, however I think i can sell mine for roughly the same price i can buy some others, Only issues is a bit of time to list on fleabay. No actual cost difference as mine are genuine landrover OEM. I've heard a lot of horror stories with spacers so was looking at the wheel offset option first as it's one less thing to go wrong. I was going to keep the 235/85s as they are new and thinner so could hopefully give me a bit more turn. I love the motor and it's a keeper for many many years. It's just a train to turn so was looking at option. What alloy wheel width do you need for certain tyres or do the tyres just sit in any width rim? Is there a rule as I can't find it on any tyre or wheel websites. Paul |

Tyre manufacturers will quote the recommended range of rim widths for a particular tyre. In general though a Boost alloy is good for anything from a 235 through to a 285, although the latter is somewhat controversial. If you are running 235/85 on Boosts your turning circle, assuming that the lockstops are correctly adjusted, should be about as good as it gets, and you may find that moving the wheels out to a 0 offset simply makes the articulation of the CV joints the limiting factor.
Almost certainly these will be urban myths, since there is nothing inherently more or less dangerous with spacers as there is using wheels with a different offset. If you use a reputable make of spacer and fit them correctly, they are entirely safe. |

Issue with spacers for me is i have no way to easily check the inner bolts without a lot of hassle. I suppose I could invest in a decent jack, but the drive is gravel and the jack I have is not man enough for the 2t defender.
it's just easier to only have to check and torque the main wheel bolts than remove the wheels and check the spacers. I would have assumes manufacturers would quote this info, but I can't really see it anywhere on online websites or online wheel shops. hence the questions as i would have thought it was quite important. |

Paul, just google (other search engines will work as well) wheel width and tyre size, plenty of options, here is just one: https://i.stack.imgur.com/jHVET.png Sold Def 90 HT 2010...Stornaway..(SOLD in Oct 2014)

Thanks McGeordie
That's 90% of the puzzle and just what i was looking for. Many many thanks I just wish all websites would add the rim width in the details. Very few seems to put on their websites. You're a star Paul |

Hmmm
https://www.4x4tyres.co.uk/16-oem-style-bo...assis=5467 has boost alloys with a width of 7 inches and the tyre package comes with 235/85/16... Totally contradicts the above info... |

There's some very hooky information in the link in McGeordie's post - to say it is conservative is an understatement. I'd be looking for more reliable and contextualised figures.
Absolutely no problems going up to 265s on Boosts (at one time this was a factory option), and many of us have run 285s without problems. |

I would say McGeordie's link relates more to road cars and tyres with shorter sidewalls than it would for 4x4 tyres, and while it shouldn't be disregarded totally, could perhaps be used as a very conservative estimate.
