    Default Talk me out of 33" tyres, or don't :)

    Afternoon All

    I am very close to purchasing 285/75/16 MT tyres for my Navara, basically 33" . Lets forget the fitment issues as I have solved these already. Research shows that with my 60mm suspension lift, 40mm body lift and steel front bumper I should have very little (if any) trimming to do to stop rubbing issues etc. I currently have 265/75/16 (31.6") tyres fitted and there's plenty room to work with after my lifts. I've listed the possible issues below and my thoughts on them:

    Fitment/Rubbing: Non-Issue as mentioned

    Performance loss: It will only be a 4% increase in diameter from my current size tyres and I feel I have plenty "power" with my current setup for how I drive so don't see this being a huge issue. I'd imagine going straight from stock tyres to 33" would hurt but I'm already used to my current "oversized" tyres. Have plans for free flow exhaust and possibly a chip/dyno tune to give me a little more kick if things get too lazy with these tyres.

    Fuel consumption: My daily commute is very short. When I do travel distance its the long road visiting friends or going on fishing trips. I'd imagine fuel consumption when cruising would remain relatively unchanged as its acceleration that's the killer here. Either way, when work is only 3km from my house consumption isn't a major concern.

    Gearing issues offroad: My low range gearing will now be affected for offroad use, perhaps with steep descents the vehicle will tend to run away a bit more. I find the 1st Lo with the compression of the turbodiesel to be pretty effective on steep descents at the moment so not sure the 4% difference in diameter will cause too many hassles here. Slow crawling will be affected too but don't do much of this. Will this be more of an issue than I imagine?

    Potential Damage: Increased strain on drive train could damage diffs, side shafts, CVs, TC, clutch etc. when going off-road. I don't have a front diff lock and don't hammer my Nav on trails so not sure how big of a factor this would really be over my current 265s.

    Knob Factor: I may be seen as a chop for having "big" tyres on a Navara

    In theory the advantages are relatively minimal, I won't lie I am doing it for the looks as much as I'm doing it for the marginal increase in certain areas of off-road performance. (How many guys can say a truck/suv with big takkies doesn't have a certain appeal) . I am going to new mags/wheels and was always keen to run mud terrains so thought might as well go big or go home considering all the other mods I am busy with. The 265's are looking a bit small with my 100mm+ total lift.

    What are your thoughts? I've definitely thought this through and I am very keen to do it but always open to constructive criticism. Either way I will hang onto the old tyres in case it's a nightmare. Can always go back and sell off the larger tyres.

    Mud Terrain tyres are just lovely. I hug mine every day. They are slightly noisy on tar. But they sure as hell looks manly.

    Big tyres looks good on any 4x4 that has been lifted. You can't have small tyres on a lifted 4x4.

    On the 2.5 or 3.0V6?
    If the 2.5, well, l'll be honest, I wouldn't.
    Have you factored in the weight gain of the 5 tyres?
    My Cost vs. Benefit graph points sharply upwards for cost with very little gains, even if it's just for the look-at-me factor.

    But, be patient, many others here will not agree with me.

    Ek sien jy noem diesel, en clutch. En 16" Dus het jy n 128kw 2.5 diesel. Ek het een gehad met 265/75/16, en alles was piekfyn, awesome offroad. Alles behalwe wegtrek teen skuiste met stopstraat en swaar sleepwa agter jou. Dan trek jy dood. Met 33" gaan wegtrek teen opdraend met sleepwa n nagmerrie wees.

    As jy egter nie sleep nie, gaan 33" net probleem wees met wegtrek teen bult, die res sal fine wees.

    If I remember correctly, Leisure Wheels mag had a 2.5 Navara fitted with 35's by Arctic Trucks shortly after they opened locally. That had no driveline mods, only a chip, if I remember correctly.

    Honestly, I have no idea how it will affect the reliability of things like the tie rod ends and CV's, but if you are willing to take a chance on that and to foot the bill for the extra fuel, why not.

    I have just taken off the (30") 265/65 x 17 Bridgestones ATRs and rims off my 140kw 2.5 Pathfinder and put on my Cooper STT tyres and rims, size (32" or actually a 31.6 inch) 265/70 x 17s. I took these tyres off the Patrol to fit 285/70 x 17 BFG MTRs on the Patrol.

    I now have two sets of 5 rims for each vehicle, one set with ATRs and one set of MTRs for the Pathfinder and the same for the Patrol. It is just so much easier just to change 5 rims with tyres already fitted.

    There is a noticeable difference on pull-away, I have to rev a bit more to pull away and even on the road, the peppy nippiness to take a gap in the traffic is no longer there either. I can't say I enjoy driving the Pathfinder when it is like that. Even with the 265/65 x 17 ATRs first gear feels a bit long on pull-away. I makes me worry about clutch life expectancy....

    Make no mistake, it stands noticeably higher and looks really macho with the 265/70 x 17 MTR tyres!

    ALSO REMEMBER! The standard wheel size in 17" on the Pathfinders and Navaras were in fact 255/65 x 17 which is a 30" tyre.

    Comparison in Overall Diameter:
    255/65 x 17 OD = 763.3mm or 30.05in
    265/65 x 17 OD = 766.3mm or 30.17in
    265/70 x 16 OD = 777.4mm or 30.61in
    265/70 x 17 OD = 802.8mm or 31.61in
    285/70 x 17 OD = 830.8mm or 32.71in
    285/75 x 16 OD = 833.9mm or 32.83in

    In Australia, 285/75R16 and 285/70R17 sizes are not too uncommon in that market segment vehicles.

    Stop conforming to the norm or worry what others think. Do it and enjoy being being different from the one half and being envied by the other half. I would do it in a heart beat if I had a lift and kit that can support this.

    For a 285 tyre you will need at least a 9" or a 10" wide rim. The standard Nissan rim is only 7" wide. Are you fitting aftermarket 16 x 9 or 16 x 10 rims to accommodate these tyres?

    A 255 (or maybe even a 265) is the absolute max width for fitment onto a 7" rim, although many tyre vs rim width tables will indicate the max is a 245 for a 7" rim.

    I have a set of 285/70/17 BF mt which I put on over weekends. They work well on the standard navara rims and only lightly rub the chassis rail at full lock.

    Rim width 7" - Absolute recommended max tyre width 245, min 225
    Rim width 8" - Absolute recommended max tyre width 265, min 245
    Rim width 9" - Absolute recommended max tyre width 285, min 265
    Rim width 10" - Absolute recommended max tyre width 305, min 285

    *recommended = by tyre manufacturers (for safe operation) for 4x4 tyres. For road car lower profile tyres they recommend tyres at least 20 to 30mm narrower on the same rim width.

    Now take those same tyres and fit them on 9" rims and see how much wider they are on the correct rim. So what you think is a 285mm wide tyre, on a 7" rim is effectively possibly only a 255mm wide tyre..... (tread on the road width is what I am talking about)

    I used 33x12.5 x 15"s (equivalent to 315) on 8-inch rims for 80k km. Never caused an issue.

    Ek vat 33x12.5x15 op n 8" rim 10 maal eerder as op n 10".

    Ek het tot laas week n stel 31x10.5x15 op n 10" gehad, net vir 2 maande lank. Wat n gemors. Death wobble calore. Hulle geruil na 8" rim, geen meer death wobble.

    The full 285mm was still in contact with the road, if I get a chance over the weekend I'll fit them and take some pics.

    I know of guys running 285's on 6.5j rims... (I will be doing the same very soon).
    And also a lot of guys run 33x12.5r15's(317? wide) on 8j rims...
