Try clearing cache and/or redownloading the mod. The wide aluminum wheels have a different model to match the extra width
Are you by any chance using this mod too? https://www.beamng.com/threads/gavril-t-series-expansion-pack.24127/page-59#post-1678790 I've had the same troubles with those combined (not 100% confirmed, but a good 90+% certainty. Try disabling that or any other non EFC mods and see if it changes. ALso do the clear cache as EFC mentioned. Good luck!
I thought that mod was still outdated. I did choose a fairly generic name for the wide wheel variants so I could change those in the next update.
They recently released a patch for 0.31 (With some real nice things in it I must say) and i started having nasrrow wide tires after installing it. Could also have influence by Bella's mods.
Did some testing on this, using your mod and still with the T-series Legacy and GTG mods T-series expansion (with .31 patches. Something is happening to the wide wheels, not sure how I can find out what mod/part migth be culprit. I'll help troubleshoot if you need me to, just tell me what to look for:
Perhaps they are really incompatible because there are no issues with the wide aluminum wheels of GTG's T-series expansion pack
I'll probably just have to check the files of the GTG mod myself. I didn't consider it as I didn't know you could still run it in 0.31
Patched just a few days ago, and I think you're right on the money about the wheel naming. The GTG separate model (tridem semi with large wheels and wide load signs) have the same name for the wheels that you have.
The extra axles and wheels have nearly no customization whatsoever (tire pressure, mainly). Perhaps you should take a look at that.
The second steer tire pressures are linked to the main steer tire pressures. The Third axle on the tridem should have its own pressure slider already.
Update 0.27.1 - Renamed Various models to avoid mod conflicts - Added tire pressure sliders for each axle.
Update 0.28 - Added Latches for the 20ft shipping containers as an option on the flatbed upfit. Available under the cargo slot of the flatbed. Also allows up to two containers loaded. - Better organized all mod files.
I'm not sure what your wanting here. Their are already fenders for all the conventional cab trucks and the cabovers have cut up variants for the extra clearance.
