The 30’s will definitely affect your low range gearing, you will have to use gear 1 where you would use gear 2, like in sand.

In my personal opinion, I don’t think so, all the guys I know who have 30’s or higher have lifts higher than 50mm, and when I say I don’t think it will fit, im talking about fitting them without having to cut so you have them without them rubbing at full flex. Also if you don’t modify your high and low range gears it will take away some of your high and low range performance. I have two sets of rims, aftermarket rims on the 30’s and oem ones on the 215’s so depending on what I will be doing, I change between the two. If you have a nice friendly tyre place, I would recommend taking the car in and testing on 1 wheel first, test it on a ramp and also test by turning the steering. Also watch my vids on tyres, i shared what I personally look for before fitting bigger tyres on optimus

@@NZninG we just set it to the standard 1.8 bar and that seems to work for us

The springs I bought that gave me a 75-80mm lift were the type c springs. I believe they are heavy duty springs

Im on a 50mm running 31s, no issues

Hello guys! 2 questions: For 30 tyres, If I wanted to keep stock bumpers, is that possible just cutting a bit in front like an inch and will fit properly?. Just wondering. 2. If I got the back ladder 30 tyre will fit or I need to remove the ladder?. Thank you!

@@jorgemidencearauz1232 if you have a lift kit on the car, im sure it could fit with slight cutting on the plastics. Wrt your ladder, it will depend on the ladder you have.

Very good question, FE Builds is all about experimenting and testing, we found that the biggest you can push to without changing gear ratios is 235/75r15 but even then, you will feel the reduction in power. With the 30’s you will battle in low range without gear reduction on technical sections and in 2h, your gear 5 will be very weak on long steep hills. We have 2 sets of tyres, 215/75R15(for technical sections and long distance highway travel) and 30’s that we just pop on when we plan on doing high speed very bad gravel roads where that extra 1.5” is needed. Optimus is a MT. I would recommend 215/75r15 but if you do high speed on bumpy terrain and jumps then get 30’s also, if you go this route, keep both sets and get a second set of rims so you can just swop them out depending on your needs

@@febuilds thanks a lot for your detail answer! Here where i live there is a lot more of technical parts and to get there you have to drive a lot in highway. I dont want (right now) to spend on gear reductions, so i think maybe max out that i will consider is 235/75R15. Again, thanks a lot.

All the tyres we got had white letters except for the new small set. But I want to paint the letters white, will do a vid on it when i get time and will share it

No, when the 30’s are on, you feel the weight. Planning to do that sometime soon
