Hi Beezer,
thanks for your effort. The tyres are good, maybe a bit too grippy for this car. Would it maybe possible, to cjange the into the original format (front 205/55 16, rear 225/50 16)?
Here's a quick tutorial as there seems to be a few questions recently related to tyres and it's a lot simpler than I suspect people realise and pretty much one of the easiest and most important fixes on the majority of mods. I'll use your Lancia 037 in its default state as an example (I'm assuming you have content manager installed for this guide to work...):
1) Download and install (instructions are in the download) the following CM tyre machine generators:

2) Go to content tab, cars and the Lancia and click the replace tyres option, then delete one of the sets of tyres and click save.
3) Now open the car's data folder and tyres.ini -> there should now be a section headed as [__CM_FRONT_ORIGINAL] and [__CM_REAR_ORIGINAL] -> In both front and rear original sections, after the third line down enter a new line and save as follows: RIM_RADIUS=0.216
4) Now go back to CM and click replace tyres again, now click the generate new ones tab in the top right. Chose whichever tyres machine is most relevant for this car, probably street 90s & 80s and drag both front and rear tyres to the left to replace the existing older ones and click save.
5) Open up the CM showroom and go to the car parameters tab, click the boxes 'Align using data' and 'Wheels'. You can now see how the wheels/tyres fit to the data model of the car in game. For this car you'll see the green data is clipping slightly through the floor, so in this case with the CM showroom still open, go back to the data folder and once again open tyres.ini and adjust the RADIUS value under the front and rear tyres sections, when you adjust the value, click save and you'll see the wheel data change in realtime on the CM showroom. For this car change the RADIUS values to 0.305 for both front and rear tyres, then enter the same figures in the front and rear original sections from step 3 above and click save. You'll now see the green outline of the wheels sits snugly against the floor instead of going just through it.
6) You now have a perfectly fitting set of tyres for this car, you can use the generator to create any set of fitting tyres as you please. For this car you'll note that fitting tyres are actually 205/35/16 and 225/35/16 instead of 205/55/16 and 225/50/16, I assume this is down to how the car is modelled, you'll find it's rare that real data actually fits a mod and on most mods, the radius will be different to avoid the tyres clipping through the floor or floating above it.
Notes:
- If the car has incorrect tyre WIDTH, you can change that as well as part of step 3). Also for mods with later version tyres you won't have to insert a RIM_RADIUS line as it will already be there, just adjust the value to suit (some general values: - 0.203 = 15in / 0.216 = 16in / 0.229 = 17in / 0.241 = 18in / 0.254 = 19in / 0.267 = 20in)
- Step 2) is sometimes unnecessary if the tyres.ini already has a original front and rear section. In cases where you only have one set of tyres originally, then replace this with any generated set and it will make the front/rear original sections appear in the tyres.ini which can then be edited.
Lastly, if any of the above is unclear then ask, I've put it as simply as I can but appreciate that everyone has a different level of expertise in these matters.
