MY2023 requires complete tyre replacement after ~42,000km. Rear tyres significantly showing greater wear (presumably due to towing a 18'7" offroad van for 20,000km around Aus). Have unsuccesfully tried to source All Terrain tyres to suit 21" rims except for Comforser CF1100AT All Terrain but based on cost I doubt they would be much chop.... If anyone has sourced 21R All Terrain tyres your assistance would be appreciated!

Old tyres which came with the vehicle were Pirelli Scorpion Zero. Alternatives I have located on-line are mixed road, semi-offroad & all weather:

Bridgestone Alenza Prestige All Season 275/55 R21 116H
Yokohama Geolandar X-CV G057 275/45 R21 100W
Michelin Pilot Sport SUV 275/45 R21 XL 110Y
Pirelli Scorpion Verde All Season 275/55 R21 116H

Do any issues arise by increasing the profile from 45 to 55?

Thanks,
Pete

275/45 R21 to 275/55 R21 is a 55mm (7.04%) increase which is not allowed by law.

Max allowable increase is +15mm - unless the vehicle is a 4WD when it can be +50mm with the proviso that the 50mm is only the increase over the smallest wheel & tyre combination available for that particular model.
