Tyre size change help!

[Vicatoren]

I am trying to make a muscle car with realy big rims, but my tyres just get super this (In with) because of the low profile, and 135 wide tyres just look horendous, so what do i do? I have unrealistic wheel size on.

Please read with open minded spirit, I'm TRUELY NOT trying to bash you.
Be aware that before I started to play this game I had NO FREAKING IDEA of what a tire size was
So while I indeed gently poke you, remember I had to go myself through the process I'll try to guide you into.

Mmm first why 135 wide ???
YOU complain the tire is thin and you choose yourself a very thin size...
So maybe understanding what you are doing first ? I would truely consider some reading there

Now ofc, you may read only the Tire Width - Aspect Ratio - Wheel Diameter parts, As only those are in game implemented.

Now you start with a car, and you want to change rims (for bigger) and a thinner sidewall of the tire on the rim... BUT you have a overall diameter to work with, as in this game you can't make changes to the body parts... so a too big wheel may look ugly in comparison of body placement.

That's where a calculator site becomes handy
Like maybe this one (complex looking at first, but once you do understand things... great tool)
https://tiresize.com/tyre-size-calculator/

Or this one (much simplier in it's display, love it...)
https://www.discounttiredirect.com/learn/tire-size-calculator

So let's say initial tire size on your car was a 225 / 75 / 14''
And you want a 245 on a 18'', you have to know what is the aspect ratio to keep around same diameter...
Closest one would be a 245 / 50 / 18''

Now IF your tire is too much on the outside of the body of the car, and you don't like the look, it's where the offset comes into play

And if I'm not misstaken (but there I could be wrong, so please correct me if I am) in this game we have only the positive offset, which makes a too wide tire beeing "pushed" more toward the interior of the car.

I hope it was what you are looking for to get the tires with the look you are after

Oh btw... just a few PERSONAL tips (so some may disagree, and it's all fine)... sorry for double post... but for visibility.

I NEVER sell my tires of a car while restoring before I have indeed made my decision and bought new tires. that way you can always quickly check what was the original size.

If restoring a car for selling, I ALWAYS repair rims BEFORE buying tires... if I break 2 rims out of 4 it's usually when I go check into my warehouse and see if I have an interseting different set of rims (that could btw differ in size, so if I buy tires first...) that I may have bought from the junkyard and repaired...

Few examples of playing with those unrealistic sizes
With front and rear wheels finally around the same diameter
look at the width difference between front and rear

and this variations between both rims and tire walls

But I think I got why you are a bit lost...
When setting "unrealistic" you get the game placing you on the tire shop at the very first width of 135. You can change it with the arrows...
Same goes with any changes you want to make.
Hope it finally make sense for you

I had the same problem, sprucing up a car from a barn. New wheels and tyre but looked pathetically stupid! Originals were 17" you can only buy 16". The low profile look doesn't suit the car, it's a bug that needs sorting as it spoils the hours of work you put into it... fixing cars to make money to upgrade your own car.
