Any advice for the correct size of tires and type of tread for steel wheels?
I have a 230GE, so wanting to minimise rolling resistance on the roads, but still wanting to go offroad (and have that aggressive looking tread pattern)

Here's a 2 photos of similar looking combinations that I'm after:

These are 235/85 I think - maybe a touch too big for the 5 1/2 wheel width. These might be 6 inch wheels

I like the thinner width of these tires, but I think the mud-terrain tread would handle badly on tar roads? These are maybe 225/80's

Any advice would be great

I have used 235/85 16's without issues for a very long time on my 280 with 5.33 diffs.

I'm fairly sure that they may be a bit of a stretch, but like I said, I had no problems.

Regards,

Arnold

On a 230GE the 235/85R16's would be too big. You would loose pull away but gain in revs at speed. This might not seem too bad but when you are loaded and get to uphills you will be sorry.
You can use 205R16, 215R16 or for a slightly wider tyre 225/75R16. They are all within spec as the vehicle came out. Speedo will not be affected too much.

I would agree with Alan, esp if you have a 5th gear.
Arnold had good power (280) and low ratio diffs. so his combo would work
Iirc the max width allowable for std. 5.5J rims is 225. (I have used 235's for many years without trouble)
Both of your photos look like 235 85 16 to me - got to love the MT's - i used a set for 120 000km but they are expensive, noisy and less good on tar.

I have just gone through this exercise for the above size and found the following:

Good looking knobby tyres - R 3200 each plus.
Good AT tyres that look like wheelbarrow wheels R1600 each plus.

I went with choice 2.

Thanks for all the feedback.
Definitely wanting to use a tire size that would have come with the car originally, something like a 215/85 or 225/75 (thanks Peter) I was hoping that the 2nd image was a 215 or 225 width. Will check what these look like at the tire shop.
I agree with the non-directional tire option, as I'll only have the 5 tires.
Alan - I'm driving around with the inherited 265/75's and hating every hill that I go up. (I drive hospital bend everyday, and my average speed is about 65km/h in third gear, foot flat).
With a few tweaks, hopefully we can go a bit faster.

It is not tire related , your car is not running properly your lack of power is engine related

I had a 230GE briefly and suspect it had a sedan head on because that thing flew like a rocket. Made the normal brakes feel very inadequate.

On my 280GE I am running LT245/75R16 Bridgestone Dueler A/T. On a recent trip to Botswana we damaged a tyre wall on a pothole and had to replace the two rear tyres with A/T tyres by Triangle.

I am looking replace the Duelers (and Dirk's advice is to replace the Triangles too).

I am looking for some advice from members regarding the suitability of the size, and the tyre type?

Thanks chaps.

I have 265/75R16 BFG K0 on widened steel rims (7.5"). Have this combination for 7 years now. No issues.

A couple of us run 235/85r16 tyres. Their circumference is very similar to the 245/75s that you have but you have a higher profile for better off-road ability

I’ve been happy with their performance in mud, snow and rocks. My sand driving has been limited, might get more exposure now with the Namibia trip.

This could be long discussion.

In my case, because I tend to go to places where I need strong tyres (that can take a lot of abuse), Buttercup is shod with M/T's. However, on my little Nissan X-Trail (my platkar), that one is shod with A/T's as I know that I should (please note my carefully chosen word "should") not get myself into places where a strong and aggressive tyre is required.

So in a nutshell - it is horses for courses. You have to make the call on where you see yourself going, and then based on that, you buy the appropriate tyres.

Obviously your car's abilities could be a guideline in this matter.

Regards,

Arnold

Been looking at tire options, and found that the proportions of the General SAG 7.50 / R16 look good. Its authentic, and also has a relatively aggressive looking tread.
Problem is that its not tubeless and I'm wondering if this is an issue compared to the newer tubeless options?
