Hi all,
A quick question for those that know how this lot works ('coz I don't, really ... yet
)
The 120 comes standard with 265/65x17 tyres on a 7J (I think) rim. No idea what, if any, offset that equates to - I think 0 ?
I put 265/70x17 Cooper STTs on as replacements - they fit perfectly, but the side lugs rubbed a bit on the front inner mudguard on full lock under compression (e.g. driving over the small bump going into my driveway). They also caught a little on the front mudflap after we trimmed it to fit the sliders - that's been fixed by cable tie-ing the sticky-out bit of the mudflap back to the body mount location
I solved the front rubbing by putting on 30mm spacers on all 4 corners - no more rubbing.
The tyres do the trick, and work well, but I suspect that after the 35mm suspension lift going in, on top of the 40mm body lift already there, that they're going to look a little lost in the wheel arches - the rear's already do.
So assuming I stick with Cooper STTs (which I most likely will do because I like them and they're not stupidly priced and do what they say on the tin), I plan to go up another size.
The current size gives me an OD of 802.8mm, or 31.6 inches. I can go to 285/70x17, which I think will fit OK, which give an OD of 830.8mm, or 32.7 inches.
I can also, for about £1.50 more each tyre, got to 33/12.5R17, which, clearly, is a 33 inch tyre. For quite a bit more I can go to 33x12.5R17 tyre - so up 2 inches but no wider.
So my questions are these:
Any thoughts / comments welcomed. The 35 inch tyres are significantly more expensive and will put too much stress on the drivetrain I suspect, so I've already mostly ruled them out - and they're getting into the 'stupid price' territory.
I've also thought about 'replaceability' in remote locations' which tends to rule out the 35 inch jobbies.
I'm leaning towards the 33/12.5R17, which are described as 'high-flotation' on the Cooper website - what the heck does that mean? They don't have quite the same load-rating as the 285/70x17, (which has the same as the 265/70x17). But maybe they're a bit more specialised and I should go with the 285/70x17's?? Sigh - decisions, decisions ...
Sorry for the long-winded posting

So my questions are these:
- Can I fit either the 285/70x17 or 33/70x17 without having to get new spacers or rims?
Is there anything else I should consider (assuming they fit in the wheel arch etc. etc.?
What are the issues (if any) around fitting the 35 inch tyres? (and remember, this is NOT a daily drive, but will be focussed towards overlanding and 'mild' laning
so I'm not too concerned about changes in fuel consumption etc. )
What, if anything, do I need to do to reset the speedo?
What, if anything, do I need to do to the rear diff?
What, if anything, do I need to tell my insurers?
