    Question Tyre advice please

    Hi All

    Currently I'm running Coopers ATC 235/85 R16 which if you do the calc is a bee's dik under 32 inch.

    I'm not that impressed with the Coopers to be honest but more to the point I'm thinking about gaining that xtra inch and going to 33"

    So my questions are;

    1. Whats the minimum width that a 33 comes in useing a 16" Alloy RR rim?
    2. What are people opinion of the best tyre to fit.
    3. Will a 33 rub on the control arms?
    4. How does the 300 TDi cope with the additional inch
    5. What does it do to your fuel consumption?
    I know a lot of you have done this excersise and I've searched and read a few threads so I'm very interested in your general opinion.

    Thanks in anticipation

    All interesting questions, but to properly give opinions we need to know:

    - what you intend to be doing (cannot possibly advise on best tyre to fit otherwise)
    - why you were unhappy with the Coopers

    the 33" will be a heavier tyre and wider. This will increase fuel consumption, especially as it's rotating mass. By how much I don't know, you'd probably need controlled conditions to notice. The gearing will be marginally higher but you are unlikely to notice, and it will have little effect on cruising economy.

    Ditto the above about recommended tyres depending usage. Since the Defender runs 32s as std you won't have problems with the 33s. You'll certainly be going wider than 235, try not to go too wide though becasue you may then start to have issues with rim selection.

    255/85/16 is a good size for Defenders, they are 33.2" in diameter, so just a bees dik over 33"

    fuel consumption, slightly better i believe

    300tdi does feel them there to some degree but still copes just fine

    no panel rubbing but i had to adjust steering stops to clear the arms at full lock.

    hard to go past maxxis bighorns if you want muds..

    silverstone do a nice A/T i am told..

    Unhappy with the cooper because of

    1. They cost a shedload and with absolutley minimal off roading 2 are now missing a lug/chipped.
    2. They are out of round, e.g there is core shift in the moulding
    3. They r a shedload noisier than I expected

    I'd suggest having a look at the Maxxis and the Silverstone A/T tyre. Both are good value and the Maxxis seem to be getting a pretty good rap.

    Have to agree with INC in all aspects except make of tyre. I know BFG are dearer than Maxxis but I paid $290ea for mine and have approx 70,000k's on them and there is STILL 10MM of tread !! I'm not sure how much the others cost but I reckon on a $ per k basis BFG blows them out of the mud !! They behave very well too and I've been told that the new BFG muddies are better on road than mine.
    All of this is of course assuming that you are after muddies.

    I'd say go for 255/85 r16 BFG mud terrains as well.

    I have had 2 sets, and use them currently. They last ages, are very good offroad, ok on road and not that expensive. You should be able to get them for $300 each on a set of 5.

    Typical ST experience except for Point 2.

    I currently run Cooper STTs which are actually quieter than the STs, and grip better offroad. I found they tore lugs in very difficult conditions though. Consider also the Wrangler MTR as a good-gripping offroad tyre. The new BFG muddie which I have briefly driven is good, but not exceptional. Need more time driving them though.

    However, for outback roads you don't need a mud-terrain tyre, an all-terrain will be fine. BFG A/Ts are a good choice there. There are others, but no personal experience.
