A prerequisite is generally a very fine-linked chain.<br> <br> For the base 185/14 and 205/70/14 are simplest it up<br> to reequip 205/14, whereby it with the TUEV under normal conditions none<br> Problems to give would be allowed to do (nevertheless beforehand questions; each examiner<br> sees the things differently.

Same sizes and tire types are recommended<br> to use in front and in the back.<br> <br> The following re-equipment, base 205/14, are theoretical<br> also for the 185-er base possible. The translation becomes however<br> long, which itself particularly with developed vehicles noticeably<br> makes.

The selection of 14 " tires starting from the size<br> 205/14 and more largely are generally limited.<br> <br> For 15"-Felgen (e.g. lack 7*15) the tire selection is something<br> more largely. Appraisal (e.g. Projektzwo) gives it for 225/70/15,<br> 235/70/15 and more broadly (starting from 215 mostly are<br> Wheel arch widenings necessarily. This likewise with the TUEV<br> clarify. Starting from 225 evtl the longer sliding door handle): Further<br> on 15"-Felgen are usable 215/75/15, 215/15, 225/75/15.<br> <br> On the 16"-Serienstahlfelge tyres 195/75/16, 195/16,<br> 205/16.<br> <br> There is surely still further wheel tires combinations<br> possible. In each case is the free movement at the rear<br> Diagonal steering wheel starting from a rolling circumference greater 2200 (dependently<br> to consider from rims and section width).

This is to be enjoyed however with caution. If itself<br> the examiner thus to an entry without limitation induce<br> , is advisable it leaves, at the latest when assembling one<br> larger tire the free movement to check again (those<br> Rolling circumferences differ within a tire size up to?<br> 2.5% and more.
