what makes it diffrent to the knobally? is it a diffrence between road and knobally?

hybrid is a "middle" between road and knobbly. typically, you'd use them on a rally track that has equal parts of tarmac and dirt.

You could always read the LFS Manual:

“Road Super” gives a little more grip than “Road Normal” for dry tarmac tracks, so there’s no decision here. The only advantages “Road Normal” tyres have are lower tread wear, so last longer, however “Road Super” tyres can be made to last as long as a full tank of fuel anyway, so you might as well get them changed at the same time as you pit for fuel.

“Road Normal” tyres should in theory give better handling in the wet, but since weather effects are a long way off, this is of no benefit at the moment. For rallycross tracks the choice of tyre is between “Hybrid” or “Knobbly”. However since all rally tracks are currently a mix between road and rally sections, it’s best to stick with hybrid tyres because although it will make the car a little slower on dirt sections, you gain speed on the tarmac sections so the “Hybrid” tyres tend to be the best compromise. Do try “Knobbly” tyres however, as you may end up faster on these tracks anyway depending on your driving style.

One use of “Road Normal” tyres at the moment is to help learn to drive some of the more powerful cars. Fitting the normal tyres to the front wheels in RWD cars, or to the rear wheels in FWD cars, will greatly reduce their tendency to power over/understeer and hence make them easier to drive. Be warned though you are reducing your cornering speeds by doing this which WILL make the car slower around the track (so lap times will never get as high as having the best tyres all around). An idea for getting used to the car, but “Super” tyres all round will end up faster once you’ve gotten used to controlling the car.

“Road Normal” tyres have however lower optimal temperature than “Road Super” tyres. Fitting “Normals” in slower cars like UF1, XFG or XRG is better option than “Supers”, because the cars are not fast enough to warm up the latter to optimal temperature while driving optimal line on the track.

thanks, i went looking for that earlier, and couldn't find it. wiki search was a fail.

Thanks, sorry for bad spelling was on mobile internet
