Hello Dave

The rough equivilant to a 750 x 16 = 235/85 x 16 (about 5mm difference in height). So you will most probably have the same power/acceleration performance you currently have

Good day all. I'm in a similar predicament. I recently bought this beauty however I think the tires are robbing me of power. They are 285/75 R16. I wish to replace them with tires that are more all terrain verses these mud terrains. So the question is what robs the wagon of power? Is it the diameter or the width or both? I am considering either 235/85 R16 or 265/75 R16. what do you all think is best?
Also what brand of tire would be best?

Hi Nicholas.
It is mainly the diameter of the tyre. I don't think the with makes too much difference. Weight between the two could possibly also be an issue.
If you have the original 230GE motor I would opt for 245/70 or 245/75R 16 as a compromise.
I run 245/75/16 on my NA 300GD with 5.33 diffs with 1.06 txfer case ratio.
I also run 235/85/16 on my OM 606 with 5.33 diffs but 0.8x txfer case ratio.
As a rough guide I always say you should be doing 100km/h @3000rpm in you 1:1 ratio gear which usually is 4th.

I am willing for you to come and swap tyres/rims for a quick test run to see if you would be happy with either.
At the same time I could test your tyres on my setup.

Helo Nicholas.

Congratulations on buying a very good looking G!

I agree with Alan, I used to have a 230GE AT and it had 245/75R 16 tyres and they worked really well.

I've just changed from 265-70-16 AT General Grabbers on my 230GE auto to Bridgestone 235-85-16 MTs. The only reason I went with the Bridgestones is because I had the set already. Diameter is pretty much the same and the speedo is spot on. The MT tyres are noticeably noisier on smooth tar roads, but that's the only downside so far. My 230GE goes like a bomb. Yes, it slows a bit on hills, but I don't see these tyres having a noticeable effect.

I run General Super All Grip 7.50-16 on my 300GD and I love them. They look good on the G without fender flares, but wouldn't work on one with flares. They're quiet on the road and they're great off road. They show almost no damage from rocks.

Hi Alan , many thanks for the information. I would love to meet with you and do a test. Are you in Gauteng?

Hi Nicholas, yes I'm in Pretoria on the Eastern side towards Bapsfontein.
Ok great I am in Midrand so not far away. What time would suit you? I will be free this weekend if possible.

fig, will you post a picture of what the General Super All Grip on your 300GD looks like?

Appreciate

When I placed the SAG 7.50x16s next to Bridgestone 235/85/16, the 235s appear to be about 50mm taller, which is significant. Others have said they are more or less the same diameter or only a 5mm difference.

What sizes tires are these?

General Super All Grip 7.50/16.

It should also be noted that although they have a crossply size, they are in fact radials.

I believe these are original fitment on early Land Rover Defenders.

I like the narrow, square look and think it complements the G.

I'm similarly trying to make my mind up since I want to change my stock 205s. (I have to admit it is only 50% wanting a slightly more capable tyre and at least 50% due to looks... but odly they seem to look less and less aenemic over time... go figure)
Leaning towards 115/85R16 with not quite as big a diameter jump as the 235/85s. Unfortunately it is not as common a size, but the Cooper AT3s look like an option - plus they have the snowflake symbol which means I can run them year round.

I ran 235/85R16 MTs on my 300GD in SA and the gearing change was a relative non-event (after I agonised over it quite a lot)
(In Germany we have a number of added complications, so I have to be a bit more careful than I was in SA )

As you probably know, in Germany you may only use 215 mm max width on 5 1/2 J rims.
235 mm is 6J.
