The rear wheels are 14x8 and the fronts are 14x7. The stock rear tires are 14x11s and the fronts are 14x9s. You do not want to put the 11s on 7" wheels...or in fact you can but if all wheels are 7" and two tires are 9" and two are 11", the OD of the tire will be different because the 11s are pinched more at the bead then the 9s and that's hard on the four-wheel-drive. The OE or stock tires are junk anyway. Might as well get a fresh set of well made tires to go with those wheels and..modernize your machine by going with all four the same size. I would go with that 5+2 wheel and put a nice 27x10x14 tire on all four. Then you can rotate then as needed because I know you use it on the roads over there and it will be necessary at some time to do that. Hope this helps.
Thank you ! So if I understand English, you advise me to keep the current rims but to put 4 tires 27x10x14.
Yes indeed in Portugal I use it also on road but just to move to the mountain.
For the moment I will just take a rim to make a spare wheel because to pass on tires 27x10x14 I have to make a change on the papers of the vehicles because I can only use wheels of 26x9x12 or 26x9x14 at the front and 26x11x12 or 26x11x12 at the back.
Thank you for your help.
